Looking at your Stack Trace there it looks like it's loaded up the friends then while parsing one of the users has come across the "CentristParty" string.  Maybe you have a friend with that as their religion or something.

Whack a Try/Catch around your GetFriends call so you don't get a big fat nasty yellow ASP.NET error page plus try stepping through in debug mode so you can see what the values are for each of the returned friends.

The error happens when i do this:

Collection<Facebook.Entity.User> friends = _fbService.GetFriends();

I assume i'll have to recompile the Facebook binaries to handle this odd value name?

Cheers for your help.

fixed the issue, the UserParser.cs in the Facebook.dll was using types for the political views and i think one of my friends has a custom political view entry so i just removed the enum for this field and recompiled the facebook.dll

if (!String.IsNullOrEmpty(XmlHelper.GetNodeText(node, "political")))
user.PoliticalView = (PoliticalView)Enum.Parse(typeof(PoliticalView), XmlHelper.GetNodeText(node, "political").Replace(" ", ""), true);

there is a link to my binary if you want it as well
