In LINQ to SQL, you can override SubmitChanges and use the method this.GetChangeSet() to get all the inserts, updates and deletes so that you can make last minute changes before it is committed to the database.
Can this be done in EF 4.0? I see there is a override for SaveChanges but I need to know the equivalent for GetChangeSet()

If you do want to implement this approach to concurrency, you have to mark all non-primary-key properties in the entity you want to track concurrency for by adding the ConcurrencyCheck attribute to them. That change enables the Entity Framework to include all columns in the SQL WHERE clause of UPDATE statements.

ObjectContext.ObjectStateManager.GetObjectStateEntries(System.Data.EntityState.Added); for inserts.
