title: Asp.Net : Best way to broadcast data from WCF service to Asp.Net client
body: <p>I need to create a high-frequency realtime web application and I would like to know the best way for doing it!</p>
  
  <p>A WCF Service hosted in a Windows Service needs to refresh browser clients (ASP.NET application) each seconds with fresh data (often with IE8).</p>
  
  <p>I've think about 2 solutions : 
  1. WCF Callback from WCF Service to Asp.Net Application server side and SignalR from ASP.NET Application server side to ASP.NET Application client side.</p>
  
  <ol>
  <li>SignalR from WCF service to Asp.NET Application client side but is it possible??? If yes, how because I just found tutorials with communication between Asp.net server side and cient side and never with signalR as server hosted in a WCF.</li>
  </ol>
  
  <p>Documentation I found is : </p>
