Entity Framework Managing entity state
Remarks
Entities in Entity Framework can have various states that are listed by the System.Data.Entity.EntityState enumeration. These states are:
Added
Deleted
Detached
Modified
Unchanged
Entity Framework works with POCOs. That means that entities are simple classes that have no properties and methods to manage their own state. Entity state is managed by a context itself, in the ObjectStateManager.
This topic covers various ways to set entity state.
