.net core is the future but Mono is still important for running legacy .net framework applications like ones that use WinForms or WPF. That’s pretty much it. Anything new should go straight to .net core.

Hm, WinForms and WPF with Wine you mean? Otherwise makes not much sense. Was WPF ever run in this combination!

Ah yeah. Mono didn’t support WPF, but Mono did support running WinForms apps natively on Linux without using Wine.
