title: SignalR causing major issues on upgrade
body: <p>After two days I've been able to finally get the new SignalR installed;however, I'm faced with another issue.</p>
  
  <p>I've either removed the specific Owin Assembly or lost reference to it some how.</p>
  
  <p>I've checked my bin, packages, and reference folders and all the original Owin naming conventions are visible.</p>
  
  <p>Anyone save me from this tragedy and show me how to fix this?</p>
  
  <p>Here is the server error returned from iis.</p>
  
  <pre><code>    Server Error in '/' Application.
