You understand database CRUD can attach a database to an app using formal database invocation methods. You might even have mastered the Entity Framework and/or have a deep understanding of ORM. Overall, in coding terms, when confronted with a new programming context you know what you want to do and how you do with UWP or Windows Forms; you just need to do it in the new context.
