Question from the Entity Framework test

You are using VS2010 and the .NET Framework 4.0 to develop an application. This application connects to a SQL Server 2008 database. You are using ADO.NET Entity Framework to model your entities.

You have enabled self-tracking entities. You need to make sure that the entity change tracking can be used to modify the database.

Which method of the « ObjectContext » class do you need to call after changes have been made to the entities?
