title: VS2012 - XDesProc hangs when Xaml file is opened
body: <p>In VS2012 whenever I try to open a xaml file (even in full XAML view) the XDesProc process keeps spinning and hangs visual studio. I tried killing it but it respawns.</p>
  
  <p>I did some search online and found that people were complaining about this in the RC release. I am not using an RC release still I see this problem.</p>
  
  <p>Is there a way to fix it?</p>
