title: Appservice for UWP Onrequestrecieved
body: <p>I am wondering when i create an appservice and create the on requestrecieved event handler is this even handler used if i use a timer trigger as well or is it only used when connected to by an appserviceconnection externally</p>
  
  <p>What i am trying to do is create one app service that is run off a trigger(to update live tiles) and also allow an application to send it information to create targeted live tiles by using an appservice connection.  </p>
  
  <p>If this is answered somewhere i have been unable to find it</p>
