title: All tests skipped in vs2012
body: <p>I had a project in vs2010 and used a testsettings file in order to include intellitrace, code coverage and test impact. After converting to vs2012, everything still worked fine. </p>
  
  <p>However, when I moved the projects in my solution to .net 4.5 from 4.0, visual studio started skipping all of my tests. I messed with the test settings and found that unchecking intellitrace caused the tests to work again.</p>
  
  <p>Does anyone know why intellitrace would cause tests to be skipped with .net 4.5? Is there any way to remedy this behavior?</p>
