In Visual Studio 2012 , Visual Studio native debugger introduces a new type visualization framework that allows customizing the way Visual Studio displays native types in debugger variable windows (watch, locals, data tips etc.). It supersedes the autoexp...

For better performance, VS Profiler requires the report to be on a local drive. If you change the report file location through Performance Session properties page (right click on performance session in Performance Explorer –> Properties –> General...

  If you install recently published VS2010 SP1 Beta , you can discover that VS Profiler team enriched Silverlight profiling user experience. Previously I published few posts about VS2010 usage for those purposes, either through VS Profiler command...

  While using Visual Studio Profiler either from Visual Studio UI or through command line tools, you may wish to collect more/different information using specific CPU Performance Counters. The collected data depends on the profiling mode. As usage...

Does your native code deals with critical sections or other synchronization primitives? Does your managed code uses C# lock statement or Monitor class? If yes, and if you would like to get a clear picture of all contentions in your application, you might...

In my previous post I showed how VS2010 Profiler command line tools can be used to profile your Silverlight 4 application, as this feature is only partially integrated with Visual Studio UI. While we are working on a full integration story, let me show...

Did you know that Visual Studio 2010 Profiler allows you to profile your Silverlight 4 applications? You didn’t? It does. This feature, however, is only partially integrated with Visual Studio UI, and you need to use command line tools to collect the...

Visual Studio 2010 brings a number of innovations to multithreaded and parallel computing. One of them is Resource Contention Concurrency Profiling. John Robbins gives a really great first look at this feature in his Wintellect VS 2010 Beta 2 Concurrency...

A recent Concurrency Hazards: False Sharing article demonstrates how VS2010 profiler can be used to detect source of cache data locality issues. To achieve this, you can sample with cache specific CPU performance counters, as long as you do not run inside...

When you run VS 2008 SP1 profiler on Intel Nehalem CPU based machine, you may experience crash of operating system (blue screen). This problem occurs because the sampling profiler uses a kernel mode driver in the operating system. However, the Intel...

Visual Studio profiler usage on virtual machines was limited so far, as it didn’t support Sampling mode in such environment. I’m glad to note that in Visual Studio 2010 you can sample your applications inside of virtual machines. VMs could be created...

VS Profiler usage in Sampling mode results in generation of VSP file. This file is, naturally, full of samples that were taken during your profiling session. You can get a Properties Window of this file by pressing F4 button: Today I would like to talk...

It may happen that when you try to attach Visual Studio profiler to a managed application, you get the following error: Error VSP1336 : Could not attach to process ID:1234 MyProcess.exe. Wrong setting of COR_PROFILER environment variable in target...

We are asked this question sometimes, especially when customers profile real world UI applications. Since it may be really confusing, I’ve decided to post the explanation of this “phenomena”. The Caller/Callee is one of views that are generated by Microsoft...

Hello, I am Maxim Goldin, and I am a developer in Microsoft Visual Studio Team System 2005. More specifically – I spend all my working hours developing a profiler , which is a part of VSTS. I joined Microsoft in June 2003 after serving Intel Corporation...
