How to add 'Microsoft.VisualStudio.TeamSystem.Data.UnitTesting' reference

I am a new to C#. I want to add 'Microsoft.VisualStudio.TeamSyst开发者_C百科em.Data.UnitTesting' reference to my project but could not find it in .Net tab. Any ideas on where I can find this or do I need to install anything else to see it in .Net tab.

Which VS version you have?

In VS 2010 family, in my case Ultimate for example it is called Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll and living here C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies\Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll.

If you have VS 2008 or 2010 express edition you still may use http://www.nunit.org/ fro unit testing.

By the way VS 2008 Architecture Edition also missing Unit Test functionality http://support.microsoft.com/kb/955869

Have a look this Unit testing in Visual C# 2010 Express?
