title: Long Polling from Server Side C#
body: <p>I'm more of a php programmer, not c#, but bear with me.</p>
  
  <p>I have an application that connects with an API that sends push messages from time to time.  It uses long polling as the mechanism.  I've looked into using signalR for this, but all the examples show the server pushing the messages.  I want the server to recieve the messages via longpolling.  Does anyone know how to do this?</p>
