Watch the full video:    • Master the Design of Functional Types...  

Modern C# supports functional types through immutable classes and records.
In the best tradition of functional design, you can define types that have no behavior whatsoever, not even a constructor you would wish to use.
Separate static factory functions would serve the purpose of a traditional constructor.
Behavior is yet another point where functional design greatly differs from object-oriented design.
The counterpart of class methods are Func delegates and delegate types.
You can implement static members that return concrete implementations of the delegates.
Why would you want to write code this way?
It is much shorter than the corresponding object-oriented model.
This code is also easier to test, takes less time to write, and comes with significantly fewer bugs.

👨 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.❤️
