📦 Analogy: Dependency Injection
Think of Dependency Injection like a **coffee machine** that doesn’t make its own milk — you inject it from outside. Just like you plug in fresh milk containers, classes receive their dependencies without needing to create them.
public class CoffeeMachine { private readonly IMilkProvider _milk; public CoffeeMachine(IMilkProvider milk) { _milk = milk; } } You don’t write "new Milk()". You let the framework provide it.
