Being able to use Events, ECS, Reflection, Dynamic code is a god send. I have written game engines in C# and I still find myself defaulting to it anytime I think about Vulkan. I even published my own bindings for it. The best thing about .Net unfortunately is also one of its worst.
The deployment and packaging situation. It’s better than it’s been but it’s still a freaking mess. A mix of undocumented cli commands and wacky xml so that I can get an amalgamated build… or if I wanted to target another OS… or something of that nature. Even adding a project reference to a project, you have to go the long way round and use the cli commands. It’s better than having to install Visual Studio Ultimate but I wish they would put some love into their VSCode extension to give .Net some more powah.
Other than that, if you need Cish speed but need to support a GUI or something, C# is a good choice. If you’re happy with HTML UI, use that and forget C#. The UI cross platform situation is basically MIA.
Go might be have been created by three Google employees, two of which UNIX idols, but the language isn't that widely deployment outside anything to do with Kubernetes.
See how much Go related content shows at Google IO. If I am not mistaken, it got a single talk this year.
Well I for one, think that using node, Python, Ruby on the backend is an anti pattern anyway.
And I certainly don't want to use a language that makes me feel like coding in Java 5, that was 20 years ago.
