title: Visual studio crashes
body: <p>I am building a Silverlight 4 application using Mvvm Light(latest version), and VS 2010 crashes every 5 minutes even less. So it is impossible to work.</p>
  
  <p>I believe it is because I am doing or there is something wrong with my MVVM implementation.</p>
  
  <p>I get this error on the designer sometimes.</p>
  
  <pre><code>An unhandled exception has occurred:
  
  [Xml_CannotFindFileInXapPackage]
  Arguments: ServiceReferences.ClientConfig

  I don't know if this is related with the crash. 
  
  ..And I found this error in the event viewer:
  Application: devenv.exe

  Description: The process was terminated due to an unhandled exception.
