The Lesson About GUID IDs I Learned the Hard Way ► youtu.be/n17U7ntLMt4
Do you pass strings and ints around your application? Nah, that's a primitive obsession!
Do you exchange enums between classes? Nah, that's an anemic domain model!
Then, why would one send raw ID values between classes and to the UI? Those raw IDs look that way because the database is fine with them, not because they are good in the domain model!
This video dissects the problem of ensuring strong typing when assigning ID values through all the application layers: in Entity Framework Core mappings, in the domain model and all the calls inside it, to Razor pages and HTML generation.
You will learn how to work with autoincrement numbers, common GUIDs, and lexicographically sortable UUIDs, each separately wrapped into a strong ID type that preserves assignment safety, including model binding to and from HTML.
