Your application uses the following code to update a database using a strongly typed DataContext:

Customer cust =
new Customer { CustomerID = "CONTO", CompanyName = "Contoso" };
db.Customers.InsertOnSubmit(cust);
db.SubmitChanges();

You must detect whether the update conflicts with changes made to the database since the query was made.

What should you do?
