У меня есть обобщенный c анонимного класса, как показано ниже: 

public class wfassignmentList : List<wfassignment>
    {
        public wfassignmentList(DataConnectDataContext db)
        {
            var query =
                from a in db.wfassignments
                group a by new

                select new

            }
        }
    }

Я пытался получить данные этого типа, например, для веб-службы, но это не работает.
