You are implementing a method that uses Entity Framework POCO entities. This method creates a new Product entity and proxy by using the ObjectContext's CreateObject method. You need to ensure that the Product is added to the data source when you call the ObjectContext's SaveChanges method.
What should you do?

Select from following answers:
Call the ObjectContext's AddObject method.
Call the ObjectContext's Attach method.
Call the ObjectContext's DetectChanges method.
Call AddObject on the ObjectContext to add the object to the object context. Do this when the object is a new object that does not yet exist in the data source.
Call the ObjectContext's Attach method to add a detached object to the ObjectContext and set the object to the Unchanged state. In the Unchanged state, the Entity Framework treats the entity key values as final. The attached entity will not have the Added state, and when SaveChanges is called, the object will not be inserted.
