When does Entity Framework open and close Database Connections?

Question

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

Answer 1

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...
