• What happens when you close an Entity Framework connection

  - by Shiraz Bhaiji

  We are using Entity Framework 1.0. In some cases we need to explicitly open connections, and then need to explicitly close connections. See http://msdn.microsoft.com/en-us/library/bb738582.aspx My question is, when we call "close" does the connection actually get closed, or is it just returned to the connection pool?

• How to add entity object to adequate entity set with object context in EF?

  - by Levelbit

  I have a problem when I add an entity object with ObjectContext.AddObject method because I can't retrieve that object with LINQ querying my ObjectContext.Person entities. I know that this new added object is stored somewhere, because it is used to update database after SaveChanges method. That's bothers me because I want to update my datagrid DataContext without saving changes unless I really want to do it. It doesn't help if I add the same object to DataContext list myself directly.
