title: facebook-C#-sdk MVC "Hello World" app - how to get access token?
body: <p>I've downloaded the C# Facebook SDK "Simple MVC Website Example" from CodePlex at:</p>
  
  <p><a href="http://facebooksdk.codeplex.com/releases/view/54371" rel="noreferrer">http://facebooksdk.codeplex.com/releases/view/54371</a></p>
  
  <p>and have successfully got it to authenticate to my test Facebook app.  But I can't quite work out how to get the access token (and I'm going to want offline access, so I only need to grab that token once, when the user first authorizes my app to grab their feed data).</p>
  
  <p>Many thanks</p>
