"Profile test" is disabled after upgrading to Windows 8

My test explorer was working flawlessly before my windows 8 enterprise upgrade but now, the "Profile test" option is disabled. Everything else is working correctly, I can also start profiling sessions without any glitch. I tried with VS 2012 update 2 and also Update 3 RC1 and no change.

Thank you for your post.

Whether you are working with ReSharper? This is a thread with the similar issue:


It seems that the issue may reproduce when ReSharper is enabled.

If it is in this case, I suggest that you try the following suggestions:

You could locate to the IDE folder then run these commands, or you can set path to the system environment.

C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE

Devenv.exe /SafeMode: Launches the IDE in safe mode loading minimal windows.

Devenv.exe /ResetSettings: Restores the IDE's default settings, optionally resets to the specified VSSettings file.

Devenv.exe /ResetAddin: Removes commands and command UI associated with the specified Add-in.

Devenv.exe /ResetSkipPkgs: Clears all SkipLoading tags added to VSPackages.

After these, you can create a new test project and a new test to avoid if there’re any problems of the old settings. If still has no help, I suggest that you try repairing your VS.

Best regards,

Thanks for your help. I tried all these commands, I tried disabling my addons, and even reinstalling Visual Studio 2012. No luck with any of these, I ran devenv with /log and I found the following exception. The file is there, so I am not sure which dependency would fail.

Could not load file or assembly 'Microsoft.VisualStudio.TestWindow.Core, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

I fixed the issue by deleting all files in C:\Users\...\AppData\Local\Microsoft\VisualStudio\11.0\ComponentModelCache
