title: How do I configure VS2012 test runner to pick up and run Gallio unit tests?
body: <p>I've recently upgraded to VS2012 to iron out problems ahead of my team.  We use Gallio 3.3 as a unit tests framework and have numerous tests written which work in VS2010.  However, VS2012 does not appear to recognise them.</p>
  
  <p>The VS2012 Test Explorer windows says "Build your solution to discover all available tests".  I have done several clean builds, and the system runs in VS2012, but no tests appear.</p>
  
  <p>Is there any configuration I need to put in, or any way I can get these tests to run in VS2012?</p>
