Hey Guys, having an issue with linq, I am basically doing the following but it is saying it is "UserProfile does not contain definition for Username" in the current context where I wrote "u.Username" but it does exist I have added UserProfile table to MyDbml.dbml and if I connect to another table it works fine.

TiamoDataContext context = new TiamoDataContext();

var user = (from u in context.UserProfiles
           where u.Username == UsernameLabel
          select u).FirstOrDefault();

I am flustered by what small detail I have missed out to get this to work, anyone have any clues it would be much appreciation.
