title: How to log in with Facebook using DotNetOpenAuth
body: <p>I have searched, read the FB developer docs.</p>
  
  <p>MVC 4, I incorporated OpenId.<br>
  Now I want to include FB login as well, just as Stackoverflow and some other site have implemented it.</p>
  
  <p>Do I create my own JS file with sample code from FB developer?<br>
  OR<br>
  Use a third party tools, which I am not aware of what to use. I did look at OAuthClient (DotNetOpenAuth-4.0.0.11165), it could not run, there was a server error and could not debug as the source file was missing.</p>
