Concrete Products (Windows & Mac):?

• WindowsButton, MacButton, WindowsCheckbox, and MacCheckbox are

concrete implementations of the IButton and ICheckbox interfaces. Each

one provides a platform-specific rendering logic.

public class WindowsButton : IButton
{
public void Render() => Console.WriteLine("Rendering Windows

Button.");

}
public class MacButton : IButton
{
public void Render() => Console.WriteLine("Rendering Mac

Button.");

}
public class WindowsCheckbox : ICheckbox
{
public void Render() => Console.WriteLine("Rendering Windows

Checkbox.");

}
public class MacCheckbox : ICheckbox
{
public void Render() => Console.WriteLine("Rendering Mac

Checkbox.");

}
