Where to find “Microsoft.VisualStudio.TestTools.UnitTesting” missing dll?

Question

I am getting following error in my C# visual studio project:

The type or namespace name \'VisualStudio\' does not exist in the namespace \'Microsoft\'

Answer 1

I got this problem after moving a project and deleting it's packages folder. Nuget was showning that MSTest.TestAdapter and MSTest.TestFramework v 1.3.2 was installed. The fix seemed to be to open VS as administrator and build After that I was able to re-open and build without having admin priviledge.
