Entity Framework 4.0 Best Practise for Creating Object Context

Question

Hi,

I would like to know what is the best practice for creating object context instance. Prior to Entity Framework, we are advised to delay the creation of connection object until the point when we need it to execute query and dispose it as soon as we are done with it in order to conserve resources.

Will this practice applicable to the ObjectContext as well ? Would the ObjectContext keep the underlying database connection intact once we instantiate the ObjectContext or once we issue the SaveChanges call?

Thanks

Regards

Yong
