Integrate a rich text editor using TinyMCE in an ASP.NET Razor Pages app, wiring in the script, API key, and a textarea with validation for create and upsert flows.

Learn to implement a menu item post handler: upload an image to wwwroot/images/menu items, generate a unique file name, and persist the item with unit of work save.
