title: socket.io vs. SignalR
body: <p>I am developing a ASP.NET MVC app deployed on Azure, and looking for a library providing asynchronous transport mechanism/fallback.</p>
  
  <p>After my own research, I've concluded that there are two well-known candidates - Socket.io and SignalR. </p>
  
  <p>My question is simple) What's the pros and cons of them? It there any good reason to use one over the other?</p>
  
  <p>thanks :)</p>
