title: PushSharp APNS Feedback Service Example
body: <p>We have implemented PushSharp for sending push notifications to our enterprise iOS devices.  This is being sent from a Windows machine and we customized the PushSharp code to be called from a console app which is scheduled to run every minute (checks SQL Server DB for push notifications to send and then sends what is returned).  This all works fine, but I have been unable to find an example of how to call the feedback service with this library.  I see there is a FeedbackService.cs class that looks to handle the connections with Apple's feedback service, but the documentation doesn't cover how it works or how you use it.</p>
  
  <p>Does anyone have a good tutorial or an example of how to use the feedback service?</p>
