I believe the smart advice says don’t go code first if you already know what you’re doing with SQL but it’s definitely sad that there’s such a huge barrier between these modes. As for DI it can definitely be used fruitfully outside of a web application, I suggest the book Dependency Injection: Principles, Practices, and Patterns if you’re curious. It covers examples from ASP.NET Core MVC to console apps to GUI.
