A Windows Communication Foundation (WCF) service implements the following contract.(Line numbers are included for reference only.) 01 [ServiceContract] 02 public interface IDataAccessService 03 { 04 [OperationContract] 05 void PutMessage(string message); 06 ... 07 [OperationContract] 08 [FaultContract(typeof(TimeoutFaultException))] 09 [FaultContract(typeof(FaultException))] 10 string SearchMessages(string search); 11 } The implementation of the SearchMessages method throws TimeoutFaultException exceptions for database timeouts.The implementation of the SearchMessages method also throws an Exception for any other issue it encounters while processing the request.These exceptions are received on the client side as generic FaultException exceptions. You need to implement the error handling code for SearchMessages and create a new channel on the client only if the channel faults.What should you do?（） [" Catch and handle both TimeoutFaultException and FaultException."," Catch both TimeoutFaultException and FaultException. Create a new channel in both cases."," Catch and handle TimeoutFaultException. Catch FaultException and create a new channel."," Catch and handle FaultException. Catch TimeoutFaultException and create a new channel."]
