title: Why doesn't Visual Studio break on exceptions when debugging unit tests?
body: <p>When I attempt to debug a unit test that fails because of an unhandled exception in my code, I expect Visual Studio to break on the unhandled exception so I can inspect the code and isolate the problem.  Instead, the IDE instantly exits debug mode and the test is listed as "Failed", leaving me to consult the test result's stack trace to find the problem.</p>
  
  <p>I've confirmed that the IDE is configured to break when any user-unhandled CLR exception is thrown.  I can only get the expected behavior if I configure the IDE to break on all thrown exceptions.  This, of course, makes normal debugging a PITA.</p>
  
  <p>Am I out of luck?</p>
