Is developing C# in Emacs viable without obsolete components?

I'm trying to develop C# in Emacs, preferring Emacs over Visual Studio and Visual Studio Code, and all the recommended components to add to Emacs (Omnisharp, emacs-csharp, etc.) seem to be obsolete. Is there an actively maintained set of configurations recommended for C#?

(My apologies if the question seems insufficient; caffeine has yet to kick in today.)

Thanks in advance.
