title: Unable to register new IConnectionIdFactory
body: <p>I'm trying to specify a new ConnectionIdFactory and have included the following code into global.asax's Application_Start method. I have references to both SignalR and SignalR.Hosting.AspNet assmeblies.</p>
  
  <pre><code>AspNetHost.DependencyResolver.Register(typeof(IConnectionIdFactory),
                                                () =&gt; new MyConnectionIdFactory());
  </code></pre>
  
  <p>The "Register" method shows a "Cannot resolve symbol 'Register'" on the editor. If I try to compile, I get </p>
  
  <p><em>'SignalR.Hosting.AspNet.AspNetHost.DependencyResolver' is not supported by the language</em></p>
  
  <p><strong>UPDATE 4/18:</strong> Has anyone done this in 0.5? I want to try it in the latest codebase, but I know the AspNetHost namespace is deprecated in 0.5.</p>
