title: SignalR $.connection is undefined
body: <p>I admit it, I don't know what I'm doing.</p>
  
  <p>I'm attempting to learn how to use SignalR and I'm following various samples online almost verbatim and I can't get pasted $.connection being undefined. I'm working in MVC 4.0 and trying to use either nuget-downloaded signalR js files or those from sample projects. These are my script references.</p>
  
  <pre><code>@Scripts.Render("~/Scripts/jquery-1.7.2.min.js")
  @Scripts.Render("~/Scripts/knockout-2.0.0.js")
  @Scripts.Render("~/Scripts/jquery.signalR.js")
  @Scripts.Render("~/signalr/hubs")
  </code></pre>
  
  <p>The scripts seem to load - I've even put alerts at the start of them which fire, but $.connection is always undefined. </p>
  
  <p>In a bizarre turn of events, I have a different project where I'm trying to use a different jQuery library and it uses $. and that object is ALSO always undefined. </p>
  
  <p>I'm just looking for any possible explanation of what I might be doing wrong. Thanks very much in advance.</p>
