Houston I have a problem...
Well, my problem is the LINQ to SQL... In determinate part of application I need create one Entity A and Entitys N relationate with Entity A. Exemple: Entity A = Provider Entitys N = Contacts So I create the Entity Purchase and add new Contact. So what I do is create an Entity A in the session and go manipulating the Entitys N of the session. When I retrieve the EntityA of the session and run the InsertOnSubmit works perfectly. But when I try to edit this entity in the same way, I can not save the relationship. My code: http://dotnetdevelopment.pastebin.com/WiWmHv10
