I am working with VS2013, .NET4.5
I was looking to use Microsoft.VisualStudio.TestTools.UnitTesting.TestCategoryAttribute on my tests to disable them in build server. I was unable to find it in Add reference -> Assemblies so I figured to use nuget package. Originally I installed it via 'Package Manager Console'.
Now I am experiencing weird issue with Microsoft.VisualStudio.QualityTools.UnitTestFramework nuget package. When I install it via Manage nuget packages at project level I can't see it in references. If I try to install it again it shows install button, but when I click it nothing happens.
If search at Solution level when it finds package it shows green 'installed' checkbox but I am unable to find it in installed packages so have no way of enabling it for projects.
I have checked packages folder and files are there.
I can manually add reference by browsing to .dll in packages folder but this does seem like a hack and I am pretty sure it will fail on build server.
And can remove it only manually by going to \packages deleting .nupkg and then removing reference from packages.config.
Have you experienced something similar (maybe with one of other nuget packages)? What was the cause? How did you solve it?
I also got this issue recently and installing Microsoft.VisualStudio.UnitTesting instead solved the issue. Make sure you reference the library in the package folder by deleting the VisualStudio.QualityTools.UnitTestFramework reference first and install Microsoft.VisualStudio.UnitTesting through nuget package manager to unit testing project.
