With new release of WinUI 3, " it will be possible to creates a Windows Runtime component written in C++/WinRT that can be consumed by any UWP or desktop app with a WinUI-based user interface, regardless of the programming language in which the app is written."
I think it can be a good replacement for Urhosharp.
Isn’t the C++/WinRT stuff hard locked onto the desktop targets and not usable with Azure, ASP, Xamarin mobile, etc?
C++/CX doesn’t appear to have fixed C++/CLI’s nasty issues with SSE/AVX either, forcing you to prune/ #ifdef your headers of any inline code using simd that the C++/CX side may touch in the glue code. Gets old really fast. I use C++/CLI bindings myself and just suck it up and turn off SSE for it.
