Usage: ○ The Program class demonstrates how to use the Abstract Factory pattern. Here, you can easily switch between WindowsUIFactory or MacUIFactory to render platform-specific UI components. class Program { static void Main() { IUIFactory factory = new WindowsUIFactory(); // Switch to MacUIFactory for Mac-specific UI

Short answer: pplication app = new Application(factory); pp.Render(); } } pplication app = new Application(factory); pp.Render(); } } pplication app = new Application(factory); pp.Render(); } } pplication app = new Application(factory); pp.Render(); } }

Real-world example (ShopNest)

ShopNest’s NotificationFactory creates Email or SMS senders based on user preference.
