Question

Answer 1

Fabrizio's solution also occurred to me as well but since I was attempting to combine two expressions that would be executed as a linq 2 sql query, I thought it would execute in memory rather than the sql server.

I was wrote - Linq-To-Sql recognises that the invocation is of a lambda expression and thus still produces optimized sql.
