Are you ready to rethink how you write immutable types in C#? In this video, we break down a seemingly simple object-oriented interface and rebuild it with a functional twist. That will reveal hidden pitfalls in traditional OOP, highlight the power of immutability, and show you how to transform apparently functional interfaces into functional types that gracefully evolve with your application.

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.❤️ ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ⚡️COPYRIGHT NOTICE: The Copyright Laws of the United States recognize a “fair use” of copyrighted content.
