//BUILDER PATTERN:
//If you have a class with many options and a big constructor. Use builder pattern
var burger = BurgerBuilder.Init(100)
.WithCheese()
.WithBacon()
.Build();
//ADAPTER PATTERN:
//An adapter pattern is used to combine 2 different classes
//Scenerio: EmployeeManager can only return results in CSV, But we need in pipe seperated format
IEmployeeManager adaptedInstance = new EmployeeAdapter();
var pipeSeperated = adaptedInstance.GetEmployess();
//FACADE PATTERN:
//Facade pattern can be used for simplified entrys to sub systems (Many internal functions)
var shoppingfacade = new ShoppingFacade();
shoppingfacade.BuyItem();
//DECORATOR PATTERN:
//Usefull to extend new functions to a class without inheriting (or if sealed)
var car = new BMW();
var discountedPrice = new DiscountCalculator(car).GetDiscountedPrice();
//FACTORY PATTERN:
//Factory pattern helps build objects so client no need to know all concreate classes
IInvoice invoice1 = InvoiceFactory.GetInvoice(1);
IInvoice invoice2 = InvoiceFactory.GetInvoice(2);
