title: error on calling signalR server method from a controller method
body: <p>i cant call a server method from a hub trough controller. i am currently getting this error because of the authorize attribute from the controller:</p>
  
  <pre><code>'AuthorizeAttribute' is an ambiguous reference between 'System.Web.Mvc.AuthorizeAttribute' and    'Microsoft.AspNet.SignalR.AuthorizeAttribute'
  </code></pre>
  
  <p>any idea why is this happening or what is the proper way of calling signalR methods from controller actions??</p>
  
  <p>here is my set up</p>
  
  <pre><code>[Authorize]
  public class UserController : BaseController
  {
  
   public ActionResult doSomething()
      {
          var hubContext = GlobalHost.ConnectionManager.GetHubContext&lt;MyHub&gt;();
      hubContext.Clients.All.BroadcastLogin(myusernm);
          return View();
      }
  }
  </code></pre>
