title: Visual Studio - Assert not stopping when fails
body: <p>Just moved from VS2010 Professional to Premium.</p>
  
  <p>When I hit a failing Assert using MSTEST, it doesn't stop in the debugger anymore (it does produce a correct fail in the Test Results)</p>
  
  <p><strong>Problem:</strong>  How to get the debugger to stop on the failing assert when I run tests</p>
