[FIXED] When does Entity Framework open and close Database Connections?

Issue

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?

Solution

Basically it opens when a request is called and closes once the results have been disposed or consumed. You can manually open/close or use the same connection using the object context...
