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.e. for Visual Studio 2013 I would reference this assembly:

Microsoft.VisualStudio.Shell.14.0.dll

You can find it i.e. here:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\BugAid Software\BugAid\1.0

and don't forget to implement:

using Microsoft.VisualStudio;
