Marks an object for deletion.
Assembly: System.Data.Entity (in System.Data.Entity.dll)
Deleting the parent object also deletes all the child objects in the constrained relationship. This result is the same as enabling the CascadeDelete property on the association for the relationship.
The method can be called on objects that are already deleted.
These examples are based on the Adventure Works Sales Model.
