ASP.NET website authentication with facebook

Question

I\'ve seen a lot of documentation about integration between ASP .NET web sites and Facebook, but I haven\'t found a simple working example, even using Facebook C# SDK.

as you say using Facebook C# SDK, then here is path and some code for canvas application:

By using sdk, you can parse signed request or cookie written by facebook js sdk

FacebookWebContext fbWebContext = new FacebookWebContext();

FacebookWebClient fbWebClient = new FacebookWebClient();
dynamic result = fbWebClient.Get("me/friends");
var friends = result["data"];
int frienCount = friends.Count;

For the client side:
