Answer
ASP.NET Core is designed around DI for clean structure, testability, separation of concerns, and consistent service creation across middleware, controllers, and background services.
Quick Answer
Built-in DI removes the need to manually instantiate services, manage their lifetimes, or pass dependencies through constructors manually. The container injects dependencies automatically. This enables: loose coupling (program to interfaces), testability (inject mocks), lifecycle management (scoped/transient/singleton), and framework integration (controllers get services injected automatically).
