You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to develop an application.
Vou use the ADO.NET Entity Framework Designer to model entities. You need to ensure that the
entities are self-tracking. What should you do in the ADO.NET Entity Framework Designer?

A.
Add an ADO.NET EntityObjecl Generator to the model.

B.
Change the Transform Related Text Templates On Save option to False.

C.
Change the Code Generation Strategy option from Default to None.

D.
Add an ADO.NET Self-Tracking Entity Generator to the model.

Explanation:
The ADO.NET Self-Tracking Entity Generator text template generates the object-layer code that
consists of a custom typed ObjectContext and entity classes that contain self-tracking state logic so
that the entities themselves keep track of their state instead of ObjectContext doing so.
Probably the best usage of self-tracking entities is when working with N-tier applications.
