You are developing a Windows Communication Foundation (WCF) service that allows customers to update financial data. The client applications call the service in a transaction. The service contract is defined as follows. (Line numbers are included for reference only.)

01 [ServiceContract]

02 public interface IDataUpdate

03 {

04 [OperationContract]

05 [TransactionFlow(TransactionFlowOption.Mandatory)]

06 void Update(string accountNumber, double amount);

07 }

10 class UpdateService : IDataUpdate

19 catch(Exception ex)

20 {

21 WriteErrorLog(ex);

22 ...

23 }

24 }

25 }

26Customers report that the transaction completes successfully even if the Update method throws an exception.You need to ensure that the transaction is aborted if the Update method is not successful.
