You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application. You use the ADO.NET Entity Framework to model entities. The application connects to a Microsoft SQL Server database named AdventureWorks. The application includes the following code segment. (Line numbers are included for reference only.) 01 using (AdventureWorksEntities context = new AdventureWorksEntities()) 02 { 03 ObjectQuery <SalesOrderHeader> orders = context.SalesOrderHeader. Where("it.CreditCardApprovalCode IS NULL").Top("100"); 04 foreach (SalesOrderHeader order in orders){ 05 order.Status = 4; 06 } 07 try { 08 context.SaveChanges(); 09 } 10 catch (OptimisticConcurrencyException){ 11 ... 12 } 13 } You need to resolve any concurrency conflict that can occur. You also need to ensure that local changes are persisted to the database. Which code segment should you insert at line 11?
