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It says my "FacebookException unhandled: session key invalid or no longer valid" and I don't know what to do.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
