You are implementing a method named DeleteProduct. This method first retrieves an Entity Framework-generated entity with a given key. You need to add code to ensure that the Product entity is deleted from the data source when you call the ObjectContext's SaveChanges method.

What should you do?

Calling the DeleteObject method on the ObjectSet or DeleteObject method on ObjectContext marks the specified object for deletion. The row is not deleted from the data source until after SaveChanges is called.

The ObjectSet's Detach method removes the object from the ObjectStateManager. This disables change tracking and identity resolution for that object. It does not mark the object for deletion when SaveChanges is called.
