  What is Dependency Injection (DI)? Dependency Injection (DI) is a design pattern used to manage dependencies between different parts of your application. A dependency is simply an object that another object relies on to do its job. DI is a way to provide those dependencies from the outside, rather than letting a class create them internally. 🤔 Why Use DI? Without DI: public class HomeController {     private TimeService _timeService = new TimeService(); // tightly coupled     public string GetTime()     {         return _timeService.GetCurrentTime();     } } ❌ The controller is directly creating the dependency. ❌ Hard to test (can’t easily replace TimeService with a mock). ❌ If the implementation changes, you have to change the controller code. public class HomeController {     private readonly ITimeService _timeService;     public HomeController(ITimeService timeService)     {   ...
