title: Determine when a Windows 8 app is launched by Notification
body: <p>I have notifications going to my application, I want to be able to take the user to that page in my application when they click on the notification or live tile (current displayed item).</p>
  
  <p>Is there a way to determine what the tile data is when your app is launched from a Live Tile or Toast Notification?</p>
  
  <p>Also, users have the ability to right click on a live tile and turn it off.  Is there a way to detect that so I can turn off sending them live tiles or does WNS handle that?</p>
  
  <p>Thanks!</p>
