title: Decode Signed Request Without Authentication
body: <p>Are we able to use the Facebook C# SDK to decode the <strong>signed_request</strong> parameter that is passed to the Facebook Tab page, <strong>without using Authentication</strong>? Basically, I am looking for a way to decode and parse the <strong>page JSON object</strong> that the signed_request contains.</p>
  
  <p>I am looking for the <strong>.NET C#</strong> equivelent to accomplishing the same type of decode in this PHP example: <a href="https://stackoverflow.com/questions/5329818/seamless-way-to-check-if-user-likes-page">Seamless way to check if user likes page</a></p>
