Yeah, but from what I saw it doesn't help much with master-detail setups? Like, inserting or updating an order with order lines etc. We rely heavily on those.
Important concepts: .NoTracking and setting the EntityState correctly ( mark as deleted, updated, ... )
Additionally, sometimes it's easier to update things granularly, instead of all at once.
I suppose the annoyance comes from updating in bulk on a POST and trying to map everything?
