Hey Jimmy when u want to implement the contract between two entities then you should use the interface when we want to use the alternate for the Threading we can use the delegates which acts as the function pointer abstract classes are same as that of interface but it can have some methods of its own not necessary that implementer should implement them all again one benefit when u dont want to break the application implementation we can use abstract classes
