refactoring LINQ IQueryable expression to remove duplicated portions of queries

Question

I have some linq queries that have redundancy I\'d like to factor out a single piece of code. These are join experssions that are IQueryable, and its important I don\'t cause t

Answer 1

Another important way to factor linq expressions is to pass expressions around, for example:

X GetSomeX(Expression> map)
