How do I delete all the entities related to a specific entity?

Question

I am using Entity Framework 4.0 and I want to delete all the entities that are pointed to by the navigation property on an entity. How can I do this?

Answer 1

You are trying to solve the problem in the wrong layer. You need to reconsider your database design specially how you maintain the referential integrity.

You need to set the "CASCADE DELETE"s of the foreign keys and reflect that in your Entity Model. Then the database will make the necessary changes to maintain the referential integrity when you delete that entity.

Answer 2

I'm not sure if I have understood your problem. but as I know .clear() method clears and removes all the navigation properties like Orders.clear()
