My pleasure. :-)
My impression about VS Code being popular is also from workplaces at several companies, VS Code was literally on every machine and VS Code project config files are nowadays checked in with project into version control. (In the past I would not have been happy about config files in version control, but I just accepted it by now.)
One more question: How to setup VIM/NEOVIM or EMACS as a descent C# IDE? AFAIK the language servers support navigation and auto completion, what about refactoring, code generation, support for build systems, hot reloading for code while debugging etc.?
It will be a pleasure, like every other year of the Linux Desktop™ for more than 20 years now! :-)
