up vote 0 down vote favorite Suppose that I inserted an entity to an entity set by calling the InsertOnSubmit method , like this : DBDataContext db = new DBDataContext(); Product product = new Product {ID = "1" , Name = "Chair"}; db.Products.InsertOnSubmit(product); // db.SubmitChanges(); I didnt call SubmitChanges intentionally . My question is , can i later find that product and delete it with DeleteOnSubmit method?: Product product = db.Products.Single(p => p.ID == "1"); db.Products.DeleteOnSubmit(product); If i cannot , then what the InsertOnSubmit method actually does ? Thank you in advance for your help. linq-to-sql share | improve this question
