You are implementing a method that uses Entity Framework to update a Product entity. You add the following code:

public void UpdateProduct(Product product)
using (AdventureWorksEntities context = new AdventureWorksEntities())


When you execute the code, you find that the product is not updated. You need to modify the code to ensure that the product is updated.
