Answer
ASP.NET Core includes a built-in DI container for service registration, lifetime management, and constructor injection. It enables cleaner architecture, testability, and decoupling across the entire framework.
Quick Answer
Rather than instantiating dependencies manually (new Service()), ASP.NET Core's built-in DI container injects them automatically based on constructor parameters. This enables loose coupling (depend on interfaces), easier testing (inject mocks), and proper lifecycle management. It's built-in so every framework feature (controllers, middleware, Razor Pages) supports it natively.
