title: Is there a way to programmatically quit my App? (Windows Phone 7)
body: <p>I'm writing a windows phone 7 app.  I have "fatal exception" handling code where I know for sure that the app is totally busted and there's no point in continuing.  (I'm hoping I never get here...).  Since there's nothing more my app can do other than quit I want the user to be able to close the app.  </p>
  
  <p>But I noticed there is no <code>System.Environment.Exit()</code> in the Silverlight 4 SDK for Windows Phone 7.  Is there another way to quit the app programmatically?</p>
