C# doesn’t have a big spotlight on it like Rust or Python, but it is a popular and very unhated language. It’s a good language that is regularly improving and has phenomenal documentation. Seriously, I’ve not gone to Stack Overflow for anything C# (outside of third-party libraries) for years; Microsoft’s documentation gives me everything I need.
I’m not the best judge, as I’ve not exactly explored a ton of languages, but I love C#.
