Storing a complex detached object graph in EF6

Question

I have the current scenario:

I\'m using EF6 Code first, and have created a data-model something like this:

public class MainObject{
  ..some properti         


        

Answer 1

I ended up using GraphDiff to solve this for me, and it works just great! This really should be built into EF, but untill it does, this is a great substitute.

To solve the example given in my question above, this will make sure that the detached graph gets saved properly (given I have a MainObject I want to save called main):

context.UpdateGraph(main, map =>map
  .AssociatedCollection( m => m.SubObjects, with => with
    .AssociatedCollection( s => s.SubSubObjects)
  )
);

context.SaveChanges();
