title: WP8 application running in background
body: <p>I'm trying to learn how to create an application on Windows Phone 8. I followed this <a href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj662935%28v=vs.105%29.aspx" rel="nofollow">tutorial</a> published on msdn.<br></p>
  
  <p>The problem is that this code doesn't work,and i don't know why. I tried to debug it. So far, i found that  the problem is <code>Application_RunningInBackground</code> method  is never triggered. Normally, it's supposed to start working when apps works in the background. Or, am i missing something ? </p>
