An object-oriented mindset is crucial to creating meaningful applications and understanding how the C# language works behind the scenes. The tricky part is that classes and structs by themselves aren't the end of the line when it comes to OOP and designing your own objects. They'll always be the building blocks of your code, but classes are limited to single inheritance, meaning they can only ever have one parent or superclass, and structs can't inherit at all. So the question you should be asking yourself right about now is simple: "How can I create objects from the same blueprint but with different implementations?"
Interfaces
One of the ways to gather groups of functionality together is through interfaces. Like classes, interfaces are blueprints for data and behaviors, but with one important difference: they can't have any actual implementation logic or stored values. Instead, it's up to the adopting class or struct...
