Mono died because Microsoft bought it out and used parts of it along with parts of regular .NET to make the modern cross-platform MIT-licenced .NET implementation that’s used both on Windows and elsewhere. There’s no need for an open source third party .NET implementation if the first party one is already open source.
A very interesting choice of language. Haven’t seen C# really used anywhere but game development and thought Mono was dead on Linux 🤔
