Description

Today I upgraded VS 2017 to 15.4.5 and it stopped discovering any tests in any of my projects/solutions.

Actual behavior

Same here with VS 15.6.4. Removed AppData/Local/Temp/VisualStudioTestExplorerExtensions folder and worked fine again. The original folder VisualStudioTestExplorerExtensions/MSTest.TestAdapter.1.2.0/bin/_common was empty, instead I had another folder with expected files VisualStudioTestExplorerExtensions/1.2.0/bin/_common.

Hope it helps!

[12/4/2017 16:26:38 Error] c:\Temp\VisualStudioTestExplorerExtensions\MSTest.TestAdapter.1.2.0/build/_common/Microsoft.VisualStudio.TestPlatform.MSTest.TestAdapter.dll This seems to be an issue with adapter dll not getting loaded from appropriate location.

@abatishchev, @twilly86 : Can you guys try deleting this folder “c:\Temp\VisualStudioTestExplorerExtensions”, restart VS and do discovery again? If this still doesn’t work, can you also try deleting “/packages” folder(containing all nuget packages required for that solution) which is created at solution level.
