You are developing a Windows application by using Microsoft .NET Framework 4 and Microsoft Visual Studio 2010.
The application will consume a Windows Communication Foundation (WCF) service. The WCF service will provide data to the application.
You plan to use the ADO.NET Entity Framework to create a data model that will be used by the application.
Another development team makes changes to the WCF service data contract.
You need to ensure that changes made to the WCF service data contract do not require the application to be recompiled.
What should you do?

A. Create a storage model based on the schema of the existing WCF service. Update the mapping file when the new version of the WCF service is available.

B. Create a conceptual model and a storage model based on the existing version of the WCF service.

C. Create a storage model based on the business model. Use a class generated from the storage model for programming.

D. Create a conceptual model based on the business model. Use a class generated from the conceptual model for programming. Update the mapping file when the new version of the WCF service is available.
