Is it possible to cascade data using Entity Framework?

Question

Entity Framework

There are two classes: "ancestor" and "heirs". The class "ancestor" has a collection of heirs. It is possible to insert data cascadingly without doing a breadth or depth traversal (keep the ancestor, get the id, update the object, and then insert all descendants):

Predok nas = new Predok{Name = "Вася"}
db.Predok.add(nas);
db.SafeChange();
//взять id, обновить вставленного предка и вставлять всех наследников

But simply:

List<Naslednik>  Nasled = new <Naslednik>();
//заполняем List<Naslednik>
var PredokIn = new Predok {Name = "Вася", Nasledniki = Nasled}
db.Predok.add(PredokIn);

Answer 1

Yes, you can.

db.Predok.add(PredokIn);

- EF understands that.
