title: Toast is not shown while application is launching in windows phone
body: <p>I am developing a Windows Phone 8 application, and I've implemented a background agent which does some work and also updates my application's Tile and shows a toast notification to the user.</p>
  
  <p>It works, except when I am launching the application (more specifically when control is in the <code>Application_Launching</code> event) in which case the Toast notification is not shown, but the Tile still gets updated. Has anyone ran into this before?</p>
