Naysawn has announced that the Visual Studio unit testing framework (MSTest) is moving into the Pro SKU of Visual Studio. That's a good start, but I want to lobby for going the whole way:

Please move the unit testing framework into the .NET framework.

And there was much rejoicing...

Of course, Brad's right that unit-testing libraries ought to move into the base library, but the VS tools are sophisticated enough to be implemented solely as VS add-ins.
