C# is more tightly coupled than C++. Everything has its place in the class hierarchy. The hierarchy is mainly composed of interfaces and classes.

Interfaces provide contracts for the implementation's capabilities, which classes then fill with life. We all know the scary legends from multiple inheritance and how it brought the diamond problem over the world once. Interfaces saved us. If you are lucky enough to use .NET 5.0 or later, you are not even required to pay the tribute of implementing their methods for each single class. Let us explore them a little more.

I never dived too deeply into SFINAE as one would find madness lurking not far away down there. With C++20 around the corner it fortunately becomes only necessary for code of former standards. Concepts bring interesting features to C++ and I deliver a basic introduction to their usage.

The alignment of documentation and code might be challenging. You either have to always keep in mind to update the relevant comments or they get deprecated really fast. Fortunately, using a powerful editor like nvim can help us with this challenge.

In C# IEquatable<> is used to implement comparison of custom classes. Different solutions exist for the proper implementation of the required interface in regard to surrounding requirements. Especially the requirement for the hashing function is not immediately obvious in the context of comparison.

It took me some time to figure out the best approach. So, here it is.
