For desktop apps specifically + functional programming, F# is probably your best bet. On Windows WPF is king, and F# works great. For desktop apps on Linux and elsewhere, you can use Xamarin, GTKSharp, AvaloniaUI...and the list goes on. Desktop apps are a strength of the .NET ecosystem.

Xamarin (the code) is open source[0]. Only the bells and whistles (live code preview, integration with VS/VS4M, etc.) are closed source. I think. [0] https://github.com/xamarin/Xamarin.Forms ; https://github.com/xamarin/xamarin-android ; https://github.com/xamarin/xamarin-macios
