  <p>Has anybody run into the problem? </p>
  
  <p>Unit tests in other Win8 class librarys or apps works fine. </p>
  
  <p>I think it's something with the solution. Yesterday everything went fine. I guess there was a Windows update, maybe that screwed things up?</p>
  
  <p>Things i've tried:</p>
  
  <ul>
  <li>Uninstalled R#</li>
  <li>Reinstalled Visual Studio 2012 RC</li>
  <li>Tried unit tests in other class library (works)</li>
  <li>Tried unit tests in Windows 8 app (works)</li>
  <li>Cleaned / Rebuild solution</li>
  <li>Debug and Release Configuration</li>
  <li>Added another Test project to the solution and unload other project(works)</li>
  </ul>
