Dependency Injection (DI) is a design pattern used to achieve loose coupling between classes and their dependencies. Instead of a class creating its own dependencies, they are injected from the outside, making the code more modular, testable, and maintainable.

In ASP.NET Core, dependency injection is built into the framework and is used throughout the application, including middleware, controllers, and services.

How DI works in ASP.NET Core:

1. Service Registration: Dependencies (services) are registered in the Startup.cs file (or Program.cs in .NET 6+), typically inside the ConfigureServices method.

2. ASP.NET Core provides three main lifetimes:

   • Transient: A new instance is created every time.

   • Scoped: A single instance is used per request.

   • Singleton: A single instance is used for the application's lifetime.

3. Service Injection: Once registered, the services can be injected into constructors where needed.

   1. Built-in Services: ASP.NET Core itself uses DI internally and allows injecting services like ILogger, IConfiguration, and DbContext.

   By using DI in ASP.NET Core, you avoid tightly coupling classes, making it easier to swap implementations (e.g., for testing) and follow SOLID principles. It also simplifies unit testing through mocking dependencies.
