title: System.Web.Routing.RouteCollection does not contain a definition for 'MapHubs'
body: <p>I follow sample from SignalR wiki page and here is my <code>Global.asax</code> :</p>
  
  <pre><code>&lt;%@ Application Language="C#" %&gt;
  
  &lt;%@ Import Namespace="System" %&gt;
  &lt;%@ Import Namespace="System.Web.Routing" %&gt;
  
  &lt;script runat="server"&gt;
  
      void Application_Start(object sender, EventArgs e) 
      {
          // Code that runs on application startup
          RouteTable.Routes.MapHubs();
      }
  </code></pre>
  
  <p>But I'm getting:</p>
  
  <p>'System.Web.Routing.RouteCollection' does not contain a definition for 'MapHubs' and no extension method 'MapHubs' accepting a first argument of type 'System.Web.Routing.RouteCollection' could be found (are you missing a using directive or an assembly reference?) \Global.asax    11</p>
  
  <p>What am I doing wrong?</p>
