Abstract classes and interfaces are essential tools in C# for building scalable and maintainable systems. This article breaks down their differences with practical examples, like crafting a reusable notification system, and explores advanced techniques like interface default implementations and factory patterns. Perfect for leveling up your software design skills!
Polymorphism sounds fancy, but at its heart, it’s just a way to treat different objects the same, as long as they share a common blueprint (like an interface or a base class). It’s what makes systems flexible and scalable—two words every developer loves to hear. Today, we’re going to explore how to use polymorphism to craft APIs that aren’t just good, but great for real-world projects.
