I've been running into a situation where devenv.exe takes 98% CPU usage until I shut it down in task manager (I've let it run for several minutes and it never seems to finish whatever it's doing).
I can't create exact steps to reproduce but it always seems to be related to Unit Test Runner. Particularly after I debug some unit tests and finish debugging. Recently it happened once when switching from all tests tab to failed tests tab in unit test runner.
Anyone else experiencing this problem?
