if I have two primary keys, i want to group by field A and field B (the p-key). Then I want to identify all rows having those two keys with the predicate in a linq where, but i can't build the predicate with fields A and B. I don't know beforehand the fields name, that's why i would like to dinamically build both keyselector and predicate
