The collection (usually, a view) to join to this view.
Expression<Func<T, TKey>> outerKeySelector

A function to extract the join key from each element of this view.
Expression<Func<TInner, TKey>> innerKeySelector

A function to extract the join key from each element of the second view.
Expression<Func<T, TInner, TResult>> resultSelector

A function to create a result element from two matching elements.
