But it only applies to IMAP accounts. It works for me. Outlook remains open in background shutting down for several minutes after having closed it. This make impossible to re-open it or to shutdown the computer, need to wait for several minutes before or to kill the process in task manager or force shutdown the pc.

I have unchecked all the add-ins without success. Any other solution? What type of email account do you have configured in Outlook? There is a known issue with IMAP accounts – outlook doesn’t close properly when you have an imap account and there is a registry key to use as a workaround. I am using Outlook with exchange server in Windows I have to keep ending task to get it to ask for my other profile. Is there a fix for this for exchange email? It does not do this on my other machine just on one of them.

Do you have any other applications – such as sync utilities – accessing Outlook data? Do you also agree that it is just ridiculous that as a user you can not kill your own tasks? What a stupid design decisions are happening at microsoft. Outlook was shut down because the restart was holding up for a long time with the comment: “Outlook is shutting down” Now Outlook will not boot up.

Using Outlook on Windows Using Outlook Malwarebytes is another Add-in that keeps Outlook open. I didn’t realize this was happening until I found that I could not open Outlook from either my taskbar icon or desktop icon.

At first, the only way I could get these icons to work was to reboot the entire system, which was a pain. After the reboot, the icons would work the first time, but they did not work after I had “exited” Outlook. Even though Outlook did not appear open on my desktop, it was running in the background, as I determined using the Task Manager. I discovered that Malwarebytes was running in my list of hidden icons bottom right corner of Win 10 screen. By right-clicking and quitting Malwarebytes, the Outlook taskbar and desktop icons worked every time.

I tested it by starting Malwarebytes up again, and the icons refused to work after closing Outlook because Malwarebytes prevented Outlook from completely closing. Malwarebytes is a nice app, so no criticism there.

Just substitute any of the other add-ins listed in the article above, and I’m sure you’ll find the same story about preventing Outlook from completely closing. Does malware bytes scan email? That should be the only reason it keeps it open – and disabling mail scanning should solve it.

We installed Shoretel’s Call Manager under the Administrator’s account and later installed Office under the user’s account. On other cases we had created a new user on the workstation and were attempting to run both apps under the new user’s account.

When we removed Shoretel’s Call Manager and reinstalled it under the account of the current user, the problem resolved and we could load and unload Outlook multiple times without any problem. In our environment Shoretel’s Call Manager only reads Outlook’s Contacts at startup to load it’s own contact information.

This should not effect one’s ability to close and then reopen Outlook especially when everything works fine at first. Then when you add in the apparent sensitivity to having another app Call Manger installed under a different user account, it makes for a very bizarre scenario.

You are also able to automate your test cases through the use of Coded UI tests and add them to your builds. So there is a lot of integration between the entire team. From within MTM, you also have access to Lab Management, which allows you to manage tests across multiple virtual environments.

We will focus on Test Case Management for now. Of course, the first step is to plan what the test team will be working on.

From here, you can create a new test case, add an existing test case, edit test cases, and change test suite properties. Behind the scenes, a test plan and a test case is just a work item.

This is where you can customize how your test cases are going to run and set environment settings. Here is the Test Settings screen: On this screen you specify the type of information that will be gathered during test runs. This is really important as it will help testers and developers communicate and re-create any issues that you run into.

You can set settings on the following diagnostic values: — Actions: What applications will be recorded for play-back — ASP. NET client proxy: Lets you collect information about the http calls from a client to a Web server used along with IntelliTrace — Event Log: Event logs and event types that should be collected.

It collects information about which methods were called by your application. When a developer touches that same method, then the test cases will be flagged to be re-run. Creating a Test case Obviously, the most important feature would be to actually create your test cases. Here is the screen for that: If you are familiar with TFS, this probably looks familiar to you.

This is where the user would enter all the steps that a tester would need to follow in order to complete a test case. This is specific to a manual test case, so the test steps should be written as human-readable as possible. You can also use parameters in order to make your test cases data-driven. This allows you to create multiple iterations.

Later on, I will show you how to use them to achieve some automation on your manual test cases. So that covers the first part of this series. Next step is Test Execution. My word it really is a dire application. What state is the test case in, has it been reviewed? Hi, I have seen that occasionally this page displays an error message.

George D. Then came Performance Improvements in. NET Core 3. NET 5. Which brings us to today. Since its main branch forked a year or so ago to be for.

NET performance for. NET 6. To get started, I created a new console application:. That yielded a net6perf. You can do so with a command like this:. Most of the results in the post were generated by running on Windows, primarily so that. NET Framework 4. However, unless otherwise called out, all of these benchmarks show comparable improvements when run on Linux or on macOS.

Simply ensure that you have installed each runtime you want to measure. NET 6 RC1 , along with the latest released downloads of. NET 5 and. Final note and standard disclaimer: microbenchmarking can be very subject to the machine on which a test is run, what else is going on with that machine at the same time, and sometimes seemingly the way the wind is blowing.

Your results may vary. Code generation is the foundation on top of which everything else is built. As such, improvements to code generation have a multiplicative effect, with the power to improve the performance of all code that runs on the platform.

NET 6 sees an unbelievable number of performance improvements finding their way into the JIT just-in-time compiler , which is used to translate IL intermediate language into assembly code at run-time, and which is also used for AOT ahead-of-time compilation as part of Crossgen2 and the R2R format ReadyToRun.

Consider a simple case:. Here we have a method, ComputeValue , which just takes an int and multiplies it by 7, returning the result. NoInlining to tell the JIT to not inline it. Compute loads the value 0x7b in hex into the ecx register, which holds the argument to ComputeValue , calls ComputeValue , then takes the result from the eax register and multiples it by 11 0xb in hex , returning that result.

We can see ComputeValue in turn takes the input from ecx and multiplies it by 7 , storing the result into eax for Compute to consume.

Now, what happens if we remove the NoInlining :. Inlining is a very powerful optimization. Of course, you also need to be careful with inlining. If you inline too much, you bloat the code in your methods, potentially very significantly. That can make microbenchmarks look very good in some circumstances, but it can also have some bad net effects.

Every call site to Int Parse will now end up carrying a potentially optimized with knock-on effects copy of the code; call it from different locations, and you now have , bytes of assembly code rather than 1, that are reused. That means more memory consumption for the assembly code, and if it was AOT-compiled, more size on disk.

But it also has other potentially deleterious affects. Computers use very fast and limited size instruction caches to store code to be run. If you have bytes of code that you invoke from different places, each of those places can potentially reuse the bytes previously loaded into the cache.

Net net, inlining is hugely powerful, but also something to be employed carefully, and the JIT methodically but necessarily quickly weighs decisions it makes about what to inline and what not to with a variety of heuristics. First, it got faster, yet there was little-to-no work done within Utf8Formatter itself in.

NET 6 to improve the performance of this benchmark. Second, the code size which is emitted thanks to using the [DisassemblyDiagnoser] attribute in our Program. How is that possible?

In both versions, the employed TryFormat call is a one-liner that delegates to a private TryFormatInt64 method , and the developer of that method decided to annotate it with MethodImplOptions. That method is a switch on the input format. Symbol , branching to call various other methods based on the format symbol employed e.

As a result, even though TryFormat gets inlined, in. Inlining also goes hand-in-hand with devirtualization, which is the act in which the JIT takes a virtual or interface method call, determines statically the actual end target of the invocation, and emits a direct call to that target, saving on the cost of the virtual dispatch.

Once devirtualized, the target may also be inlined subject to all of the same rules and heuristics , in which case it can avoid not only the virtual dispatch overhead, but also potentially benefit from the further optimizations inlining can enable. For example, consider a function like the following, which you might find in a collection implementation:. A previous release of. Default to compare each element of the tuple :. But devirtualization improvements have gone well beyond such known intrinsic methods.

Consider this microbenchmark:. NET Core enabled the JIT to avoid the boxing operation here from casting a value type to an interface it implements and emit this purely as a constrained method call, and then a subsequent release enabled it to be devirtualized and inlined:. Length call.

NET Note in. Length call, with the assembly now limited to moving the answer 3 into the return register:. A multitude of other changes have impacted devirtualization as well. One of my favorite features of. NET in multiple forms over the years. But the implementation in. The general idea behind profile-guided optimization is that a developer can first compile their app, using special tooling that instruments the binary to track various pieces of interesting data. They can then run their instrumented application through typical use, and the resulting data from the instrumentation can then be fed back into the compiler the next time around to influence how the compiler compiles the code.

However, with tiered compilation, a whole new world is available. You can see where this is going. That enables gathering all of the interesting data during tier 0. Note that the core libraries that make up.

To enable instrumenting the core libraries as well, you can disable ReadyToRun:. Then the core libraries will also participate. You may hear folks working on. When compiled on. NET 6 normally, we get this:.

A few things to notice, beyond it being much longer. That enables better use of instruction caches and minimizes loads necessary to bring in likely-unsed code. Now at the beginning of the method, we see:. This is the magic. Range inside of the Enumerable implementation.

MoveNext method, devirtualized. Not only that, but it decided it was profitable to inline that MoveNext method. That MoveNext implementation is then the assembly code that immediately follows. The net effect of this is a bit larger code, but optimized for the exact scenario expected to be most common:.

It can actually reduce code size in various circumstances by choosing to not apply optimizations that might otherwise increase code size e.

It can optimize for type casts, emitting checks that do a direct type comparison against the actual object type rather than always relying on more complicated and expensive cast helpers e. The list will continue to grow over time as the JIT learns more and more how to, well, learn. There are other categories of optimization critical to high-performance C and.

NET code, as well. For example, bounds checking. One of the great things about C and. NET is that, unless you go out of your way to circumvent the protections put in place e. You can see that with a simple example:. Length against the index value stored in the r8d register. If the index is equal to or greater than the array length, it jumps to the end of the method, which calls a helper that throws an exception.

Of course, such bounds checks add overhead. NET libraries do rely on avoiding this kind of overhead wherever possible. If you write:. Every release of. NET sees the JIT become wise to more and more patterns where it can safely eliminate bounds checking, and. NET 6 follows suit. Consider the following benchmark:. This represents relatively typical code you might see in some lower-level formatting, where the length of a span is checked and then data written into the span.

NET 6 makes that a whole lot better, thanks to the aforementioned PRs. NET 5, this benchmark would result in assembly like the following:. The JIT in. NET 6 knows that, too:. Much better. Those changes then also allowed undoing some hacks e. In previous releases, there was an issue in the JIT where an inlined method call could cause subsequent bounds checks that otherwise would have been removed to now no longer be removed.

This PR fixes that, the effect of which is evident in this benchmark. For example, consider this code:. However, doing such a bounds check on each iteration of the loop adds an extra comparison and branch on each iteration. However, as with other bounds checking removal optimizations, the JIT is looking for very specific patterns, and things that deviate and fall off the golden path lose out on the optimization.

NET 6 the loop is now cloned, as can be seen from this benchmark:. Not just bytes, but the same issue manifests for arrays of non-primitive structs. Consider a loop like:. In other words, change the while into a do.. Now consider the same situation with the inverted loop. We then enter the do.. Summary: we saved two jumps. What about constants?

Folding can happen at various levels of compilation. If you write this C :. Folding can also happen in the JIT, which is particularly valuable in the face of inlining.

If I have this C :. Based on whatever their needs were, the developer of Contains string, char decided that it would very frequently be called with string literals, and that single character literals were common. Now if I write:. The implementation of ContainsSpace string, char is then exposed to the fact that string s is ” ” and char c is ‘ ‘. It can then propagate the fact that s. Length is actually the constant 1 , which enables deleting as dead code everything after the if block.

Neat, right? NET 5 that introduced the ability to treat “literalString”. Length as a constant highlighted thousands of bytes of improvements in the generated assembly code across the core libraries. But a good example in. The methods being changed in this PR are expected to be called from C compiler-generated code with literals, and being able to specialize based on the length of the string literal passed effectively enables multiple implementations of the method the JIT can choose from based on its knowledge of the literal used at the call site, resulting in faster and smaller code when such a literal is used.

But, the JIT needs to be taught what kinds of things can be folded. Consider the Microsoft. ConsoleFormatter abstract base class. It exposes a protected constructor that looks like this:. Now look at one of the built-in types derived from it, like JsonConsoleFormatter :. Note that base ConsoleFormatterNames. Json call. Json is defined as:. As mentioned earlier, thanks to tiered compilation, static readonly s initialized in tier 0 can become consts in tier 1.

This was enabled in previous. NET releases. For example, you might find code that dynamically enables or disables a feature based on an environment variable and then stores the result of that into a static readonly bool. When code reading that static field is recompiled in tier 1, the Boolean value can be considered a constant, enabling branches based on that value to be trimmed away.

For example, given this benchmark:. The aforementioned PR builds on that capability by enabling null folding for such values. Consider a library that exposes a method like:. Default passed as an argument.

NET 6, you can see those first two instructions are still there, and the last three instructions are still there, but the middle four instructions test , jne , mov , mov have evaporated, because the compiler is now able to propagate the non-nullness of the static readonly and eliminate completely the comparer??

Default; from the inlined helper. Most of the Math methods can now participate in constant folding, so if their inputs end up as constants for whatever reason, the results can become constants as well, and with constant propagation, this leads to the potential for serious reduction in run-time evaluation.

Math docs , editing it to create a method that computes the height of a trapezoid. Note the time spent for. NET 6 has dropped to nothing, and the code size has dropped from bytes to Because the entire operation became a single constant. NET 5 assembly looked like this:. Pow on top of a bunch of double addition, subtraction, and square root operations, whereas with.

NET 6, we get:. There were additional folding-related improvements. Sometimes, though, improvements are much more focused, with a change intended to improve the code generated for a very specific pattern. And there have been a lot of those in.

Here are a few examples:. The trouble with this, however, is that in order to call the ThrowIfNull method with a string literal, we end up needing to materialize that string literal as a string object e. If the check were being done inline, the JIT already has logic to deal with that, e. But here are a few key statements from her post to help shed some light on the terminology:. Regions are much smaller units, they are by default 4MB each. Same with free spaces in gen2 and LOH — you might have some free spaces in gen2, it would be nice to use them to allocate some large objects.

We do decommit on a segment but only the end of the segment which is after the very last live object on that segment denoted by the light gray space at the end of each segment. And if you have pinning that prevents the GC from retracting the end of the segment, then we can only form free spaces and free spaces are always committed memory. But that requires bookkeeping to remember which parts in the middle of a segment are decommitted so we need to re-commit them when we want to use them to allocate objects.

And now we are getting into the idea of regions anyway, which is to have much smaller amounts of memory being manipulated separately by the GC.

Sometimes performance optimizations are about eliminating unnecessary work, or making tradeoffs that optimize for the common case while slightly pessimizing niche cases, or taking advantage of new lower-level capabilities to do something faster, or any number of other things.

But sometimes, performance optimizations are about finding ways to help bad-but-common code be a little less bad. To do that, at its core a thread pool needs two things: a queue of work to be processed, and a set of threads to process them. We can write a functional, trivial thread pool, well, trivially:.

Boom, functional thread pool. But… not a very good one. The hardest part of a good thread pool is in the management of the threads, and in particular determining at any given point how many threads should be servicing the queue of work.

NET ThreadPool has multiple mechanisms in place for determining how many threads should be in play at any point in time. First, it has a starvation detection mechanism. Thus, we end up blocking every thread in the pool, waiting for the thread pool to detect the starvation and inject another thread, which the repro then dutifully blocks, and on and on, until finally there are enough threads that every queued work item can be running concurrently.

You can see the output here; pay attention to the timestamps on each work item, where you can see that after ramping up very quickly to have a number of threads equal to the number of cores, it then very slowly introduces additional threads. In response, the thread pool becomes much more aggressive about increasing its target thread count while the blocking persists, and then immediately lowers the target count again as soon as the blocking has ended.

Running the same console app again on. Interestingly, this improvement was made easier by another large thread pool related change in. NET 6: the implementation is now entirely in C. In previous releases of. As of. This should make further improvements and optimizations easier and enable more advancements in the pool in future releases. One of the things you find a lot in multithreaded code, whether direct usage in low-lock algorithms or indirect usage in concurrency primitives like locks and semaphores, is spinning.

That makes it challenging for tuning the behavior of higher-level code written using spin loops, which core code in the runtime and key concurrency-related types in the core libraries do.

To address this discrepancy and provide a consistent view of pauses, previous releases of. NET have tried to measure at startup the duration of pauses, and then used those metrics to normalize how many pauses are used when one is needed. However, this approach has a few downsides. NET process invocations that happen every day. To address this, the aforementioned PR changes its scheme.

Rather than measuring once at startup for a longer period of time, it periodically does a short measurement and uses that to refresh its perspective on how long pauses take. This should lead to an overall decrease in CPU usage as well as a more up-to-date understanding of what these pauses cost, leading to a more consistent behavior of the apps and services that rely on it. One notable and long overdue change is enabling Task.

When async methods were added in. But Task. This has led to one of two commonly-seen occurrences: either a developer using Task. FromResult recognizes this deficiency and has to maintain their own cache for values like true and false , or a developer using Task. This adds a tiny bit of overhead a branch or two when Task.

NET 6 that is likely to impact a lot of. NET code, directly or indirectly. This requires some backstory. We can see that if we compile a simple async method:. This builder type is used in the generated code to create the builder instance via a static Create method , to access the built task via a Task instance property , to complete that built task via SetResult and SetException instance methods , and to handle the state management associated with that built task when an await yields via AwaitOnCompleted and UnsafeAwaitOnCompleted instance methods.

Most developers should never see these types in any code they read or write. One of the downsides to this model, however, is that which builder is selected is tied to the definition of the type being returned from the async method. Why would you want to change the builder? There are a variety of reasons someone might want to control the details of the lifecycle of the task, but one of the most prominent is pooling.

As outlined in the blog post Async ValueTask Pooling in. NET 5 ,. That experiment is complete and the environment variable removed for. In its stead, this capability is supported in a new form in. NET 6 and C If we change our previous example to be:. We can see that with a simple benchmark:. Note the allocation per call dropping from bytes to 0. Two reasons. First, it does create a functional difference.

Task s are more capable than ValueTask s, supporting concurrent usage, multiple awaiters, and synchronous blocking. If consuming code was, for example, doing:. Code analysis rule CA is meant to help avoid such code, but that alone is insufficient to prevent such breaks. Second, as you can see from the benchmark above, while the pooling avoided the allocation, it came with a bit more overhead. And not shown here is the additional overhead in memory and working set of having to maintain the pool at all, which is maintained per async method.

There are also some potential overheads not shown here, things that are common pitfalls to any kind of pooling. For example, the GC is optimized to make gen0 collections really fast, and one of the ways it can do that is by not having to scan gen1 or gen2 as part of a gen0 GC.

Since the entire purpose of pooling is to keep objects around for a long time, those objects will likely end up being in these higher generations, and any references they store could end up making GCs more expensive; that can easily be the case with these state machines, as every parameter and local used in the method could potentially need to be tracked as such. Beyond these new builders, there have been other new APIs introduced in. NET 6 related to tasks.

This is useful in replacing a fairly common pattern that shows up and that, unfortunately, developers often get wrong with developers wanting to wait for a task to complete but with either or both a timeout and cancellation. For example, this:. WaitAsync to replace a similar implementation that existed inside of SemaphoreSlim. WaitAsync , such that the latter is now both simpler to maintain and faster with less allocation.

NET 6 also sees the long-requested addition of Parallel. On the subject of CancellationToken , the cancellation support in. NET 6 has also seen performance improvements, both for existing functionality and for new APIs that enable an app to do even better.

That led to a really neat but complicated lock-free implementation that involved quite a bit of allocation and overhead. If you were in fact registering and unregistering from the same token from lots of threads in parallel, the implementation was very efficient and resulted in good throughput. This PR recognizes this reality and reverts the implementation to a much simpler, lighterweight, and faster one that performs better for the vast majority use case while taking a hit if it is actually hammered by multiple threads concurrently.

CancellationToken also has new APIs that help with performance. This gets a bit tricky, however, if CancelAfter is used or if the constructor is used that takes a timeout, as both of those cause a timer to be created, and there are race conditions possible between the timer firing and someone checking to see whether IsCancellationRequested is true to determine whether to reuse the instance.

The new TryReset method avoids this race condition. Those are some of the bigger performance-focused changes in threading. There are a myriad of smaller ones as well, for example the new Thread. Exchange and Interlocked. CompareExchange when used with nint IntPtr or nuint UIntPtr by enabling them to reuse the existing intrinsics for int and long :.

NET app uses types from the core System namespace, and so improvements to these types often have wide-reaching impact. There have been many performance enhancements to these types in. Guid is used to provide unique identifiers for any number of things and operations. The ability to create them quickly is important, as is the ability to quickly format and parse them.

Previous releases have seen significant improvements on all these fronts, but they get even better in. The net result is a very nice increase in throughput:. I love seeing tables like this. NET 5, and then another 2. NET 5 to. Just one small example of how the platform gets better every release.

NewGuid has never guaranteed that the values generated would employ cryptographically-secure randomness, however as an implementation detail, on Windows NewGuid was implemented with CoCreateGuid which was in turn implemented with CryptGenRandom , and developers starting using Guid. NewGuid as an easy source of randomness seeded by a cryptographically-secure generator. On Linux, Guid. Moving on in System , Version is another such example of just getting better and better every release.

TryFormat had been using a cached StringBuilder for formatting. For example, it had been using Int TryFormat to format each of the int version components Major , Minor , Build , Revision , but these components are guaranteed to never be negative, so we could actually format them as uint with no difference in behavior. Why is that helpful here? One of my personal favorite sets of changes in.

NET 6 is the overhauling of System. There are many ways performance improvements can come about, and one of the most elusive but also impactful is completely changing the algorithm used to something much faster.

In this case, the PR improves three specific cases significantly:.

Our bet, based on reviewing use cases in a variety of code bases, is this overall will be a very positive win. Also for vectorization, previous. NET releases saw vectorization added to various algorithms in System.

NET 6 is string. One of the biggest string-related improvements, though, comes from the new interpolated string handler support in C 10 and. If I write:. With C 10 and. You can see the impact of the changes with the aforementioned examples turned into a benchmark:. For an in-depth look, including discussion of various custom interpolated string handlers built-in to.

Performance improvements can manifest in many ways: increasing throughput, reducing working set, reducing latencies, increasing startup speeds, lowering size on disk, and so on. Anyone paying attention to the performance of. NET will also notice a focus on reducing allocation.

Beyond that, though, there are almost always real tradeoffs. In fact, it can make things worse, such as if the overhead of renting and returning from the pool is higher than expected especially if it incurs synchronization costs , if it leads to cache problems as something returned on one NUMA node ends up being consumed from another, if it leads to GCs taking longer by increasing the number of references from Gen1 or Gen2 objects to Gen0 objects, and so on.

However, one place that pooling has shown to be quite effective is with arrays, in particular larger arrays of value types e. Shared being used everywhere. Shared being as efficient as possible, and this release sees several impactful improvements in this area. Probably the most visible change in this area in. Shared will cache. But then that trimming was added, and the limit was never revisited… until now. The pool is also split into two layers. The first layer is stored in thread-local storage, where each thread can store at most one array of each bucket size.

The second layer is itself split into Environment. ProcessorCount stacks, each of which is logically associated with one core, and each of which is individually synchronized.

Upon returning an array, a similar path is followed, with the code first trying to return to the thread-local slot, and then proceeding to try to find space in one of the stacks. The trimming implementation in. This can lead to some rarely-used arrays sticking around for a very long time, negatively impacting working set. On top of these changes around what can be cached and for how long, more typical performance optimizations have also been done.

This entailed paying attention to where and why bounds checks were happening and avoiding them where possible, ordering checks performed to prioritize common cases e. A good deal of effort in. NET 6 has gone into fixing the performance of one of the oldest types in. NET: FileStream. Every app and service reads and writes files. Or when flushing its buffer, even when flushing asynchronously, those flushes would end up doing synchronous writes.

Combined, this has meant that, with a few exceptions, the FileStream code has remained largely untouched, until now. NET 6 sees FileStream entirely rewritten, and in the process, all of these issues resolved. All the while, additional PRs were flowing in to optimize various conditions. In the end, all of this adds up to huge maintainability benefits for FileStream , huge performance improvements for FileStream in particular for but not limited to asynchronous operations , and much better scalability for FileStream.

Here are just a few microbenchmarks to highlight some of the impact:. All of these static methods accept a SafeFileHandle , which can now be obtained from the new File. OpenHandle method. NET Blog soon. WriteAllTextAsync and makes it faster with less allocation this benchmark of course also benefits from the FileStream improvements:.

That upgrade brings with it various performance improvements , including code paths that make better use of intrinsics. Unfortunately, as an implementation detail, DeflateStream was in fact trying to return as much data as was requested, by issuing as many reads against the underlying stream as it needed to in order to make that happen, stopping only when it decoded a sufficient amount of data to satisfy the request or hit EOF end of file on the underlying stream.

This is a problem for multiple reasons. Second, and more impactful, is it effectively prevents DeflateStream from being used in any bidirectional communication scenario.

Imagine a DeflateStream wrapped around a NetworkStream , and the stream is being used to send and receive compressed messages to and from a remote party. The PR also fixes one more performance-related thing. One issue scalable web servers need to be cognizant of is memory utilization. Moving on, for System.

Pipelines , a couple of PRs improved performance. Beyond that, there were a variety of small improvements. ValidateBufferArguments and Stream. ValidateCopyToArguments , which, in addition to eliminating duplicated code and helping to ensure consistency of behavior, helps to streamline the validation logic using a shared, efficient implementation of the relevant checks.

It goes without saying that networking is at the heart of services and most significant apps today, and so improvements in networking performance are critical to the platform. At the bottom of the networking stack, we have System. One of my favorite sets of changes in this release is that we finally rid the System. SendAsync and Socket. These changes not only reduced the size of the assembly, reduced dependencies from System.

Then for. None as an argument to ConnectAsync and AcceptAsync. Passing CancellationToken. With that, I get the following, for an additional reduction:. Then, as in the previous example, I can try adding in the additional CancellationToken argument:. Other new overloads have also been added in. The net result is a nice reduction in overhead for these operations, beyond the improvements in usability.

The internal SocketPal. The fewer and smaller fields we can have on these state machines, the smaller the resulting allocation will be for asynchronously completing async methods. Just focusing on fields, the C compiler will produce for Example1 a type like this:.

The answer has to do with order of operations. FromResult That means it must compute Process someParameter before it computes await Task. But Process someParameter returns an int value; where should that be stored while await Task. FromResult 42 is being processed? On the state machine. So, back to the cited PR.

Look familiar? Dns is a relatively thin wrapper for OS functionality. It provides both synchronous and asynchronous APIs. This ends up blocking that other thread for the duration of the operation, which inherently limits scalability.

It can also be a real bottleneck for something like DNS. Typically an operating system will cache some amount of DNS data, but in cases where a request is made for unavailable data, the OS has to reach out across the network to a DNS server to obtain it. If lots of requests are made concurrently for the same non-cached address, that can starve the pool with all of the operations performing the exact same request. This adds a small amount of overhead for individual operations, but significantly reduces the overhead in the bursty, problematic scenarios.

By default, operations on Dns can return both IPv4 and IPv6 addresses, but if you know you only care about one or the other, you can now be explicit about it. Doing so can save on both the amount of data transferred and the resulting allocations to hand back that data.

Moving up the stack, we start getting into specifying URLs, which typically uses System. Uri instances are created in many places, and being able to create them more quickly and with less GC impact is a boon for end-to-end performance of networking-related code.

The internal Uri. ReCreateParts method is the workhorse behind a lot of the public Uri surface area, and is responsible for formatting into a string whatever parts of the Uri have been requested e. Path UriComponents. Query UriComponents.

Fragment while also factoring in desired escaping e. It also unfortunately had quite a knack for allocating char[] arrays. Shared for longer lengths, while also cleaning up some code paths to make them a bit more streamlined.

The impact of this is visible in these benchmarks:. UriBuilder is also used in some applications to compose Uri instances. As a result, UriBuilder is now also lighterweight for most uses:. As noted previously, I love seeing this continual march of progress, with every release the exact same API getting faster and faster, as more and more opportunities are discovered, new capabilities of the underlying platform utilized, code generation improving, and on.

Now we get to HttpClient. One key area is around header management. Previous releases saw a lot of effort applied to driving down the overheads of the HTTP stack, but the public API for headers forced a particular set of work and allocations to be performed. But the biggest impact in this area comes from the addition of the new HttpHeaders.

This has both a functional and a performance benefit. Now if we run Enumerate and EnumerateNew on. SocketsHttpHandler maintains a pool of connections that remain open to the server and that it can use to service future requests. By default, it needs to scavenge this pool periodically, to close connections that have been around for too long or that, more relevant to this discussion, the server has chosen to close. NET 5 that enables an arbitrary Stream to be provided for use with a connection, there may not even be a Socket involved at all.

In such situations, the only way we can be notified of a connection being closed is to perform a read on the connection. Thus, if we were unable to poll the socket directly, we would issue an asynchronous read which would then be used as the first read as part of handling the next request on that connection , and the scavenging logic could check the task for that read to see whether it had completed erroneously. Now comes the problem. The fix is to use zero-byte reads.

Then, only once that operation has completed, the actual initial read is issued, which is both necessary to actually get the first batch of response data, but also to handle arbitrary Stream s that may return immediately from a zero-byte read without actually waiting.

SslStream has long supported zero-byte reads on it, but it did so by in turn issuing a read on the stream it wraps using its internal read buffer. That means SslStream was potentially itself holding onto a valuable buffer, and on Windows pinning it, even though that was unnecessary. SslStream has seen multiple other performance-related PRs come through for.

This can help reduce the chattiness of ReadAsync calls, making better use of buffer space to reduce frequency of calls. The question then is, what happens to that request if, while waiting for the new connection to be established, one of the existing connections becomes available? Up until now, that request would just wait for and use the new connection. This should both improve latency and response time, and potentially reduce the number of connections needed in the pool, thus saving memory and networking resources.

This has led us to discover where things worked well and where more work was needed. This should significantly help with performance in particular on networks with reasonably-high bandwidth along with some meaningful delay in communications e. The original code employed a single, long array of tuples, which required the C compiler to generate a very large function for initializing each element of the array; the PR changed that to instead be two blittable uint[] arrays that are cheaply stored in the binary.

CreateFromStream was introduced in. Thus, any improvements we make to that managed implementation the internal ManagedWebSocket benefit both client and server. But there were two significant changes worth examining in more detail. The first is websocket compression. Adding compression increases the CPU cost of sending and receiving, but it decreases the amount of data sent and received, which can in turn decrease the overall cost of communication, especially as networking latency increases.

This app is creating a loopback socket connection and then layering on top of that a websocket connection created using WebSocket. That way, we can see how much data ends up actually being sent.

When I run this, I get results like the following:. That could be a good tradeoff if communicating over a real network with longer latencies, where the additional few hundred milliseconds to perform the compression and decompression is minimal compared to the cost of sending and receiving an additional 10MB. The second is amortized zero-allocation websocket receiving. However, as previously discussed, C 10 and.

NET 6 now have opt-in support for pooling with async methods. On my logical-core machine, this code:. Reflection provides a very powerful mechanism for inspecting metadata about.

NET assemblies and invoking functionality in those assemblies. That mechanism can incur non-trivial expense, however. While functionality exists to avoid that overhead for repeated calls e. NET 6 does in multiple ways.

A variety of PRs targeted reducing the overhead involved in inspecting attributes on. NET types and members. Code often looks up information beyond attributes, and it can be helpful for performance to special-case common patterns. A given MethodInfo will cache the array, but this would still result in an extra array for every individual method inspected. This PR fixes that. Reflection is valuable not just for getting metadata but also for invoking members.

Reflection is going to pass the object[] of arguments you pass to MethodInfo. However, if a caller erroneously mutated the array concurrently with the reflection call, such mutation could happen after the type checks occurred, enabling type safety to be violated, anyway.

Another very common form of dynamic invocation is when creating new instances via Activator. CreateInstance , which is usable directly but is also employed by the C compiler to implement the new constraint on generic parameters.

CreateInstance implementation in the runtime, employing a per-type cache of function pointers that can be used to quickly allocate an uninitialized object of the relevant type and invoke its constructor. Another common operation is creating closed generic types from open ones, e. Finally, sometimes optimizations are all about deleting code and just calling something else that already exists. IsPrimitive measurably faster:. Of course, reflection extends beyond just the core reflection APIs, and a number of PRs have gone in to improving areas of reflection higher in the stack.

DispatchProxy , for example. Even as a lot of the low-hanging fruit was picked in previous releases, developers contributing to. NET 6 have still managed to find meaningful improvements, some in the form of optimizing existing APIs, and some in the form of new APIs developers can use to make their own code fly.

The PR improves the performance of creating one dictionary from another, by enabling the common case of the source dictionary and the new dictionary sharing a key comparer to copy the underlying buckets without rehashing. And CollectionMarshal. These can be used to avoid duplicate lookups as well as avoid potentially expensive struct value copies. Indexing into these collections performs a binary search through a tree of nodes, and each layer of the traversal was performing a range check on the index.

But for all but the entry point check, that range validation is duplicative and can be removed, which is exactly what the PR does:. NET 5 , while also reducing code duplication. The latter PR adds a MemoryExtensions. Default as an intrinsic. Compare to devirtualize when T is a value type. A new Enumerable. Take that accepts a Range as well as an ElementAt that takes an Index.

In addition to then enabling the C 8 range syntax to be used with Take , it also reduces some overheads associated with needing to combine multiple existing combinators to achieve the same thing.

TryGetNonEnumeratedCount , which enables getting the count of the number of items in an enumerable if that count can be determined quickly. This can be useful to avoid the overhead of resizes when presizing a collection that will be used to store the contents of the enumerable. A lot of work has gone into crypto for the. NET 6 release, mostly functional. However, there are have been a handful of impactful performance improvements in the space.

CryptoStream was improved over the course of multiple PRs. As in the earlier discussion of DeflateStream , CryptoStream now also can complete a read operation once at least one byte of output is available and can be used for zero-byte reads. CryptoStream works with arbitrary implementations of ICryptoTransform , of which one is ToBase64Transform ; not exactly cryptography, but it makes it easy to Baseencode a stream of data.

The interface expects that input is processed in blocks of a particular fixed number of input bytes which then yield a fixed number of output bytes, e. ToBase64Transform encodes blocks of three input bytes into blocks of four output bytes. Historically, ToBase64Transform returned false from CanTransformMultipleBlocks , which then forced CryptoStream to take the slower path of processing only three input bytes at a time.

ToBase64Transform uses Base EncodeToUtf8 , which is vectorized for fast processing, but three input bytes per call is too small to take advantage of the vectorized code paths, which ended up making ToBase64Transform quite slow. Even as CryptoStream improves in. I previously mentioned improvements to System.

Random in. If you need cryptographically-secure randomness, System. RandomNumberGenerator is your friend. However, the Old case here is already improved on. NET 6 than on previous releases. The RfcDeriveBytes class enables code to derive bytes from passwords, and historically this has been done by instantiating an instance of this class and calling GetBytes. NET over the last several years to improve its performance. Many of these changes on their own have a profound and very measurable impact to some scenario.

Sometimes these changes make one specific change in one place e. NET to get better and better. There are dozens of such changes in. Why does that matter? One reason sealing helps is that virtual methods on a sealed type are more likely to be devirtualized by the runtime. If the runtime can see that a given instance on which a virtual call is being made is actually sealed, then it knows for certain what the actual target of the call will be, and it can invoke that target directly rather than doing a virtual dispatch operation.

Note the code gen difference. BenchmarkDotNet actually issues a warning a good warning in this case about the resulting metrics as a result:.

In order to measure the cost of a benchmark, it not only times how long it takes to invoke the benchmark but also how long it takes to invoke an empty benchmark with a similar signature, with the results presented subtracting the latter from the former.

Before launching your project in Dev Spaces for the first time, configure the Azure subscription and AKS cluster that you wish to use. Also, select the space where you wish to run the project. Typically, your team runs the latest stable version of the entire application in the default space.

Then, you run your version of the service you are working on in a child space of the default space. There is now no need to run the other services in the child space; Dev Spaces automatically routes calls from your service to the stable versions of the services running in default. For more information on how to set this up, see the team development tutorials in the Azure Dev Spaces documentation. Once you have selected the correct subscription, cluster, and space, click OK to proceed with the Dev Spaces configuration.

If you select a cluster that does not already have an associated Dev Spaces controller, click OK in the following dialog box to create one automatically. Controller creation takes about 2 minutes.

You can click on the Background Tasks button in the lower left corner of the Visual Studio window to see the status. Dev Spaces will synchronize your code to Azure, build a container image containing your code, and deploy it to your AKS cluster using the Helm chart defined in your project.

Visual Studio will open up a remote debug connection to the service running in the cluster so you can interact with it just as you would when debugging a service running locally. This release includes improvements to workload size and Android build performance and reliability, as well as enhancements for Xamarin.

Android and Xamarin. Forms productivity. We made performance improvements aimed at reducing the time it takes to create a new Xamarin project so you can start building your apps faster. We also now include the NuGet packages used by the templates as part of the workload installation in order to reduce package restore time, especially in low bandwidth or offline situations.

You can now see more detailed build progress information when building your projects. Clicking the background tasks icon in the bottom left corner during a build will display the current build target that is running. This can be useful for determining if the build is still running but a target is taking a long time to complete.

You no longer have to build your project for the Xamarin. If you have custom controls in your XAML file, you might need to build your project to preview those, or opt them into design time rendering.

You can now swap between different Android and iOS devices to preview your Xamarin. Forms XAML on using our new device drop-down menu. You can now edit the most common attributes of Xamarin. Forms controls, cells, and layouts in a property panel and see those changes reflected immediately in your XAML. We updated the Xamarin. Forms templates to use the latest Xamarin. Forms release and also added a new template option for a Xamarin.

Forms Shell app. Shell aims to reduce the complexity of apps while increasing developer productivity and focusing on rendering speed and memory consumption. This template gives you a bootstrapped Shell app for Android and iOS.

In Visual Studio version In Visual Studio , Android emulator images are easier to create. We’ve also continued to work with the Windows team in the Windows 10 October Update, version , to improve the performance of the Android emulator when running on Hyper-V. We have released a set of initial build performance improvements.

As of today, Xamarin. Android 9. Check out our Xamarin. Android Fast Deployment has up until now provided faster incremental deployment times by skipping over rebuilding or redeploying the Android package. Enhanced Fast Deployment expands support for fast deployment to cover both shared native libraries and classes that inherit from Java. Fast deployment builds that use these new enhancements will only need to generate a new.

Application or Activity subclass. These enhancements are not yet enabled by default in the current preview. Android now supports the latest Android dex compiler d8 and code shrinker r8. For more details on d8 and r8, check out our documentation. As part of this effort, we have also improved the messaging that the designer provides while it is loading. Alongside these improvements, the Android Designer now natively supports Android Pie 9.

When using IntelliSense to add a widget to a layout, a full snippet experience is now provided so that required attributes can be supplied from the start. We have added smart commenting and uncommenting for Android XML layouts. We are releasing a new, streamlined, developer-centric experience when connecting Team Explorer to an Azure DevOps project.

Focus on relevant work items by filtering and pivoting your view based on work items assigned to you, ones that you’re following, ones where you’re mentioned in the discussion, and ones based on your activity. Create a local branch from a work item which will automatically relate the work item to the changes made to that local branch.

This is the default experience. Should you want to switch to the legacy experience, you can by setting the Work Items experience in Visual Studio. Note that this new experience is only true for Git repos. The new experience for TFVC repos will available in a following update. Search for work items when doing a mention in the pending changes commit message.

For more details, see the View and add work items using the Work Items page. If you are trying to solve the problem of Outlook not loading, this story from administrator could point you in the right direction. The following is a short list of add-ins which are reported to keep Outlook running after it’s closed. Before uninstalling or disabling add-ins, check for an updated version.

It may fix the problem. In Outlook and newer, go to File, Options, Addins. Office SP2 addresses the problem and forces Outlook to close. Setting Outlook’s ” Empty deleted items when closing ” option can also cause Outlook to close slowly.

If the ‘Empty deleted’ setting is set via GPO , you’ll need to disable it. SRS send and receive profile file appears to keep Outlook open we don’t believe it affects newer versions of Outlook. Find and rename the SRS for the profile. She also created video training CDs and online training classes for Microsoft Outlook. The regedit file doesn’t appear to work with Microsoft I have also disabled the AVG email scanner, to no effect.

But it only applies to IMAP accounts. It works for me. Outlook remains open in background shutting down for several minutes after having closed it. This make impossible to re-open it or to shutdown the computer, need to wait for several minutes before or to kill the process in task manager or force shutdown the pc.

I have unchecked all the add-ins without success. Any other solution? What type of email account do you have configured in Outlook? There is a known issue with IMAP accounts – outlook doesn’t close properly when you have an imap account and there is a registry key to use as a workaround. I am using Outlook with exchange server in Windows I have to keep ending task to get it to ask for my other profile. Is there a fix for this for exchange email? It does not do this on my other machine just on one of them.

Do you have any other applications – such as sync utilities – accessing Outlook data? Do you also agree that it is just ridiculous that as a user you can not kill your own tasks? What a stupid design decisions are happening at microsoft. Outlook was shut down because the restart was holding up for a long time with the comment: “Outlook is shutting down” Now Outlook will not boot up. Using Outlook on Windows Using Outlook Malwarebytes is another Add-in that keeps Outlook open.
