When I instance my "Entities" object in Entity Framework, and make a couple of queries using that Entities object, what happens to connections? Does it open a connection when I instance the object, and close it when I dispose of it? Or does it open and close a connection for each single query I execute? In either case, is it possible to change it so that it does the other thing?

When does Entity Framework open and close Database Connections?
