title: Execute a Windows Phone 8.1 Application after deactivation
body: <p>I know about the Windows Phone 8.1 Applications lifecycle: <a href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/ff817008%28v=vs.105%29.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windowsphone/develop/ff817008%28v=vs.105%29.aspx</a></p>
  
  <p>But, is it possible to keep active the application when it is not used (after deactivation)?</p>
  
  <p>Is it possible to realize a WP8.1 App that sends some data to a Server at predetermined time intervals? Is it possible to execute code in the App, when it is deactivated?</p>
