Microsoft.VisualStudio.Profiler Namespace

 

The Microsoft.VisualStudio.Profiler namespace enables you to programmatically control performance data collection from within the application. This approach is useful, for example, if you want to collect performance data in the scope of a function or you want to avoid gathering performance data of a larger framework in which your code is executing. Another example where this approach is useful is, if you want to gather performance data of a specific thread from a group of threads.

These APIs are not supported in Sampling mode for Windows 8 and later versions.
