Unchanged

The object has not been modified since it was attached to the unit of work or since the last time that the IUnitOfWork.SaveChanges method was called.

Added

The object is new, has been added to the unit of work, and the IUnitOfWork.SaveChanges method has not been called. After the changes are saved, the object state changes to EntityState.Unchanged.

Deleted

The object has been deleted from the unit of work. After the changes are saved, the object state changes to EntityState.Detached.

Modified

One of the scalar properties on the object has been modified and the IUnitOfWork.SaveChanges method has not been called. After the changes are saved, the object state changes to EntityState.Unchanged.
