title: Call SignalR Hub from Backend Business Layer
body: <p>I have an MVC website sitting onto of some fairly hefty business objects.  My MVC Controllers call Manager objects which conducts and delegates work off to other sets of objects.  </p>
  
  <p>Basically the code is deep server side, while a Hub in a way is just like a Controller in that it is fairly close to the client side.</p>
  
  <p>Is there a way to execute SignalR methods based on a reference to the Hub passed to these Manager objects?</p>
