The following error shows if I try to open any Fine Code Coverage menu item (View > Other Windows > Fine Code Coverage, Tools > Options > Fine Code Coverage > General). In general Fine Code Coverage is not working.
The 'OutputToolWindowPackage' package did not load correctly.
The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\User\me\AppData\Roaming\Microsoft\VisualStudio\17.0_57b64d9b\ActivityLog.xml'.
Restarting Visual Studio Could help resolve this issue.
Continue to show this error message?
Steps to recreate
Attempt to open View > Other Windows > Fine Code Coverage
Attempt to open Tools > Options > Fine Code Coverage > General
Current behavior
Error when trying to use Fine Code Coverage. Unable to get any coverage information.
Expected behavior
Should be able to access above menu items without error. Should get code coverage results.
I've added relevant ActivityLog.xml. I've also attached the MEF errors as FineCodeCoverage shows up a lot there (this was from a fresh run of VS with no project open). Clear the MEF Component Cache did not help.

This also seemed like it could be related:

The issue is with the version of the Visual Studio Sdk that FCC is using.
If you can update visual studio I believe there should be no issues. ( regarding the loading of Microsoft.VisualStudio.Threading, Version=17.1.0.0)
I am currently working on a feature branch that has a dependency to the earlier version of the Visual Studio Sdk so as to prevent this issue / not forcing a visual studio version in the manifest.
