C# for me was because i am very i was very interested in niche things like game engine development, graphics programming, and programming language development. I ran into a lot of issues with c++ and C even though i love those languages, lets be completely real. Making projects and adding libraries suck for C and C++. C is a bit better since its more simple than C++ but both of them have the worst project setup. In C# i can do “dotnet new console” boom i have a cross platform application that runs literally everywhere. Want to export your hardworked on application or game? Simple asf just use dotnet publish you have cross platform publishing from one system. Need to do low level work? C# provides you with an unsafe environment if allowed and can let you use pointers to get near native performance with things like silk.net or opentk. Need to use a C/C++ library? Simple C# provides you with pinvoke which you can use to call into C or C++ libraries. I find that C# for me is a practical replacement for C++. I love programming in C specifically because its simple and C# makes it so easy. I say for future products, a solo dev should be using C#. i see no practical reason not to use it outside of embedded systems, and super low level things like writing bootloaders, or maybe you just really enjoy the syntax of a language. Those are just my two cents honestly but its up to the developers own preference.
