You define an Entity Data Model that maps the insert, update, and delete operations of the Product entity type to stored procedures. You create a method that retrieves a Product entity and changes its Status property. You need to update the data source, ensuring that the stored procedure mapped to the update operation is called.

What should you do?

The Entity Framework enables you to specify stored procedures to be used when modifying entity data. These stored procedures replace the methods generated by the Entity Framework. Stored procedures are called implicitly, so no changes are required to the data model defined in the conceptual schema or existing application code. Simply call the ObjectContext's SaveChanges method and your mapped stored procedures will be called instead of the method generated by the Entity Framework.

The ObjectContext's AcceptAllChanges method accepts the changes on all associated entries in the ObjectStateManager so their resultant state is either unchanged or detached. It does not persist any changes to the data source, including changes made by mapped stored procedures.
