DI is a design pattern that allows objects to receive their dependencies from external sources rather than creating them.

Benefits:

  • Decouples components
  • Improves testability
  • Enhances maintainability

Implementation Example (Manual DI):

public class EmailService {
    public void Send(string msg) => Console.WriteLine("Sent: " + msg);
}

public class Notification {
    private readonly EmailService _emailService;
    public Notification(EmailService service) {
        _emailService = service;
    }

    public void Notify(string msg) => _emailService.Send(msg);
}

In .NET Core, use built-in DI container via Startup.cs or Program.cs.
