Answer 1

You can use reflection:

using System.Reflection;

// ...

public override IPizza CreatePizza(PizzaType pizzaType, params object[] parameters) {
            return (IPizza)
                   Activator.CreateInstance(
                        Assembly
                             .GetExecutingAssembly()
                             .GetType(pizzaType.ToString()),
                        parameters);
        }
