Microsoft Facebook.dll Error: Incorrect signature (

Dec 19, 2009 at 12:15 PM


I can not get any user information or friends.
I always resived this error.

I can see the "UserId" and even the profile photo. but nothing else.
not where the problem lies.

I checked the Facebook API documentation and Microsoft DLL documentation and I can not solve it.
Could anyone help me?
Thank you very much.

This is the code:
Dim ConnectSession As New Facebook.Session.ConnectSession(ApiKey, Secret)
Dim Api As New Facebook.Rest.Api(ConnectSession)
Dim mUser As New Facebook.Schema.user

mUser = Api.Users.GetInfo() <---- Here is where the error occurs
Label1.Text = ConnectSession.UserId
Label2.Text = mUser.first_name

This is the error:
Incorrect signature
