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.

19. You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
The application design specifies the following components:
A user interface implemented as an ASP.NET 3.5 Web application
A Microsoft SQL Server 2005 database to store business data
A Windows Communication Foundation (WCF) service that authenticates users that have their credentials
stored in the SQL Server database
A business data service to transfer data between the user interface and the SQL Server database
In future releases, the application must also be able to authenticate business partners who use
non-Microsoft directory servers to store user credentials.
You need to ensure that the application design meets the extensibility requirements.
What should you do?
A. Implement the business data service as a WCF service.
B. Host the Web application on multiple load-balanced Web servers.
C. Add an abstraction layer between the user interface and the authentication service.
D. Implement database objects that store the corporate user credentials in the same SQL Server database
as the business data.
