title: Windows Phone App Background HTTP Connectivity
body: <p>I am working on developing a non-VoIP Windows Phone application that needs to have a background HTTP connection to be notified when new messages are received.  I noticed for Windows Store apps, there is an example for ControlChannelTrigger that allows you to connect an HttpRequestMessage and will send a push notification to the app when data is returned by the http request.</p>
  
  <p>Is there a similar concept that I can use for Windows Phone, because just using a Periodic Task really isn't good enough.</p>
