I use version 3.0.2 of the facebook API, but I get the same error when using version 3.0.1.
I have setup an IFrameApplication on facebook, but I get the following error when trying to pull som data:


IFrameCanvasSession session = new IFrameCanvasSession(apiKey, secret);
Api api = new Api(session);

long userId = session.UserId;
api.Session.UserId = userId;

var result = api.Users.GetStandardInfo(userId.ToString(), new List<string>(){"first_name"});

Can anyone point out what I do wrong?

Thankyou in advance :)

I found out I was for some reason using a wrong secret key. :)
