Project category data into a select list for the product upsert form by transforming categories into select list items with text and value using EF Core projections.

Learn how view bag provides a dynamic wrapper around view data, enabling runtime binding without compile-time safety, and compare it with view data for passing data from controllers to views.

Debug and fix returning to the view in mvc by repopulating the category dropdown when the model state is invalid, preserving the product view model data and highlighting server-side validation.
