title: Facebook authentication using Facebook C# SDK in MVC
body: <p>Are there any good tutorials for beginners for a simple fb log in and log out in MVC? I have tried some tutorials and none of them have worked fully for me. </p>
  
  <p>I would like a tutorial like <a href="http://www.codeproject.com/script/Articles/ArticleVersion.aspx?aid=206707&amp;av=328595" rel="nofollow">this</a> but using Facebook C# SDK and also the tutorial doesn't run for me. After some debugging in _LogOnPartial.cshtml the "response.session" is null after a user has logged in.</p>
