Whatever happened to XNA + Silverlight + Windows Phone?
Silverlight's last Visual Studio is 2015 (2017 doesn't support it by default and not sure about addons).
XNA has a Silverlight app option for Windows Phone, is there anyway to forget the app and make it run in a browser? Silverlight seems dead or dying and is probably best for XNA/MonoGame developers to avoid and is probably a nightmare for any past XNA users(?).
This seems like a working example, although I haven't tried it, XNA on Silverlight for those interested:
As for the post's solution(Web Demo), it doesn't run on Windows 10's or Windows 10 Mobiles' Edge Browsers. Haven't tried Internet Explorer...
