Entity Framework - Object Services Level. The ObjectStateManager.

posted by  mneon (8)  11 months ago (mtaulty.com)

When you look at an ObjectContext (or something derived from it) in the Entity Framework you'll spot that it has a property on it called ObjectStateManager which is of type ObjectStateManager.

This type is vital to making object services work beyond just querying the database. With the ObjectContext, you can grab objects from queries and you can then modify them, delete them and, additionally, you can add objects to the context.

Nothing happens in the store until you call ObjectContext.SaveChanges
