Dependency Injection in ASP.NET Core Explained
Dependency Injection (DI) is a foundational concept in ASP.NET Core — and mastering it is key to building clean, testable, and maintainable applications. In this in-depth guide, we’ll break down what DI really is, how it works under the hood in .NET, and how to apply it effectively in both Minimal APIs and Controllers. We’ll cover real-world use cases, interface-driven design, common pitfalls, and advanced patterns like factory delegates and conditional service registration.
