title: No source code available when debugging WP8?
body: <p>When I debug and step any windows phone app on my virtual machine I get the "No Source Available", "The current thread is not currently running code or the call stack could not be obtained".
  This is regardless if I debug on the device or the emulator.<br>
  It seems like it breaks on the correct breakpoints thou, and continuing works fine.<br>
  Stepping through server code works fine.</p>
  
  <p>The virtual machine is just set up for this and only contains Windows 8 (updated), Visual Studio 2012 Pro (complete, updated), Google Chrome, Start8 and Windows Phone SDK 8.0.</p>
