You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application.
You 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.
Change the Code Generation Strategy option from Default to None.

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

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

D.
Add an ADO.NET EntityObject 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.
