Session Key Problem...

Jun 4, 2009 at 11:13 PM

I am just getting started working on a desktop Facebook application using the Facebook Developer Toolkit and Microsoft Visual C# 2008. I have an API and a Secret Key and have entered and have tried to find a solution to this problem but I can't find one. It says my "FacebookException unhandled: session key invalid or no longer valid" and I don't know what to do. I am new to developing with this toolkit.

Here's the code that it highlighted:

 friendList1.Friends = facebookService1.friends.getUserObjects();

Can someone please help me here. Thanks -- BrettB87

You need to verify whether the session key is valid or not. Have a look at I have included the utility class that I use.
