VS 2008
From Richard's Wiki
When creating a "Test" project in Visual Studio, the following element
is added to the csproj xml in the very first PropertyGroup element:
<ProjectTypeGuids>{3AC096D0-A1C2-E12C-1390-A8335801FDAB};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>
If you created your test assembly by hand, say by creating a new Class Library
and adding a reference to Microsoft.VisualStudio.QualityTools.UnitTestFramework,
this element will not be in your csproj file and visual studio will ignore all
the tests located inside. Add the element and all will be good again.
