MS Test Error : Test skipped/Test host process exited unexpectedly

I get this occasionally – esp. when I’m killing the tests part way through a debug session. The trick is to kill the VSPerfMon process that hangs around.

Or the way I do it:

c:\>tasklist | findstr /i VSPERFMON
VSPerfMon.exe    6500 Console                    1     23,192 K
c:\>kill -f 6500
