title: facebook comments system for asp.net mvc 2 website
body: <p>I know this sort of question has probably been asked many times before, but I can't find an answer.</p>
  
  <p>I have an asp.net mvc 2 website for which I've built a membership system based on the standard asp.net membership provider.
  I would like to add to that website a comments system where users, in order to comment on a topic, will be able to log into their facebook account (from within my website), and then make the comment. The comment should be shown on my website of course, and also in their facebook account, on their wall, or something similar, with something like "user x posted a comment on website y".</p>
  
  <p>So my question is how do I build a facebook based comment system for my asp.net mvc 2 website using facebook c# sdk, or any other way ?
  Code samples or tutorial links would be great, thanks ...</p>
