Do you know how to design a base class so no derived class can add a bug to it later? Does this sound like dark magic? Let it be so!
It is a lesson that so many young programmers learn the wrong way: that of applying class inheritance. If you trust mainstream books, you should specialize a class by deriving from it and overriding virtual methods. Sure, but that will take you down the spiral of endless bugs. Welcome to the realm of real-world programming!
Watch this video to learn a better way of doing inheritance - the way safe from bugs, misunderstandings, and confused calls.
The class design technique you will learn from this video is based on abstract methods and virtual methods with empty bodies in the base class. The base class will stand responsible for the order and validation of specialized parts of its operation implemented in the derived class.
Once you master this technique, you will never make a bug caused by overriding. Not because you will be smarter than you are now but because you will be designing classes with no place left to put a bug into them!

👨 About Me 👨
Hi, I’m Zoran, I have more than 20 years of experience as a software developer, architect, team lead, and more. I have been programming in C# since its inception in the early 2000s. Since 2017 I have started publishing professional video courses at Pluralsight and Udemy and by this point, there are over 100 hours of the highest-quality videos you can watch on those platforms. On my YouTube channel, you can find shorter video forms focused on clarifying practical issues in coding, design, and architecture of .NET applications.❤️
