What should you do?

You create a Windows Communication Foundation (WCF) application by using Microsoft Visual Studio 2008 and the .NET Framework 3.5.
You create a WCF service by using the following code segment. (Line numbers are included for reference only.)

01 [ServiceContract]
02 public interface IContosoService
03 {
04 [OperationContract]
06 void ProcessTransaction();
07 }
09 public class ContosoService : IContosoService
10 {
11 public void ProcessTransaction() {
12 try {
13 BusinessComponent.ProcessTransaction();
14 }
15 catch (ApplicationException appEx)
17 {}
18 }
19 }

The BusinessComponent.ProcessTransaction method will only throw exceptions from the ApplicationException type.
You plan to debug the WCF service. You need to ensure that the WCF service meets the following requirements:
– Detailed exception information is provided to the client application.
– Subsequent calls can be issued to the service by using the same proxy intance after an exception is caught in the client application.
