Care to elaborate on what would make C# a bad language?
They have in fairness fixed a lot of the worst aspects of this by adding basically a second language to it but e.g. I massively prefer writing F# if purely because if I want to do something I can just to it rather than first implementing public static DoThing : IDoThing
public static DoThing : IDoThing
In other words, C# is a bad language because you don't like it?
What does prevent you from "just do it" in C# without extra classes and interfaces?
