Need help with Web Service : "Session key invalid or no longer valid"

Aug 23, 2008 at 5:27 PM
Hi,
I'm new to developing in silverlight and your toolkit.
When I'm trying to use the code from your sample for a web Service I'm getting an exception when I'm calling

_fbService.GetFriends();

 
from the ' public UserJSON[] GetFriends(string api, string secret, string session, string userid) ' method of the web service.
I followed the instructions from the User Guide to pass the userId and sessionKey from the default.aspx page to the silverlight app,
and I keep getting "Session key invalid or no longer valid",
any ideas?
btw, i'm using version 1.2 because of an authantication exception in the RC2.
