How to make further progress from here? What would be next step to get friends list?
string APIKey = ConfigurationManager.AppSettings["API_Key"];
string APISecret = ConfigurationManager.AppSettings["API_Secret"];
Facebook.Session.ConnectSession connectsession = new Facebook.Session.ConnectSession(APIKey, APISecret);
Facebook.Rest.Api api = new Facebook.Rest.Api(connectsession);
You’re really close. All that is left to do is call the GetLists method in the Friends namespace.
Here’s the link to the REST api docs. It should help you find other functions. Another way is to just use visual studios IntelliSense. Type api. and visual studios should give you a list you can navigate through.
