title: SignalR issues with existing website
body: <p>When I am trying to add SignalR in our existing web application (with MVC 4) I am getting below error message on page load.</p>
  
  <p>Message: Unable to get value of the property 'signalR': object is null or undefined

  <p>I tried to navigate to signalr/hubs jquery and it seems to be working fine as my client hub class is available in the javascript. </p>
  
  <p>Any pointers on what i might be doing wrong.</p>
