LINQ to Entities: Why can't I use Split method as condition?

Question

I have the following LINQ query:

var aKeyword = \"ACT\";
var results = from a in db.Activities
              where a.Keywords.Split(\',\').Contains(aKeyword)         


        

Answer 1

You may want to look at this question about L2E and .Contains for a solution that should be more efficient than guessing at a superset before filtering client side.
