Weird problem with Visual Studio - when I change the name of a unit test, it does not update

I've run into a weird problem with Unit Tests in Visual Studio 2010 that I can't solve (is this a bug in Visual Studio?).

If I edit the name of a unit test, it is not updating in the "Test List Editor" view. If I add a unit test using the normal method, it doesn't add it to the list of unit tests.

Any ideas on what开发者_StackOverflow might be possibly be causing this, and perhaps brainstorming some method to redo my Unit Test project to fix this problem?

Found the problem: I have ReSharper installed, and it unexpectedly took over the default unit testing framework provided by Visual Studio 2010, when an auto version upgrade took place. I am currently running the unit tests using the ReSharper unit testing plugin, and everything works fine. This is not to say that it's necessarily ReSharper's fault, I did opt in to use the enhanced unit testing framework when I installed it a month ago (and I can opt out by switching it off in options).
