The Facebook Developer Toolkit works great with VB.NET.
However, it does not support the authentication of the APIs and the GUI APIs.
You can get a list of friends with this code (I'm not sure if the formatting for the Writeln() method is correct):
' autheticate first For Each item As Facebook.Schema.user In api.Friends.GetUserObjects Console.Writeln("uid: {0}", item.uid) Console.Writeln("picture: {0}", item.pic_small) Console.Writeln("first name: {0}", item.first_name) Console.Writeln("last name: {0}", item.last_name) Next
