Woah, this brought back memories.
As I recall, Microsoft was always the most friendly toward treating web apps as if there were native apps, listing them as first-class citizens in their stores and such, but I’m not sure how much of a thing that is anymore since they aren’t much of a player in the phones and tablets world anymore (although I do think the Surface Duo is cool). But surely a truly native Windows app is .NET and C# and whatnot.
When I was an SDET in Windows Mobile, I worked on both 6on6 (IE6 on WM6) and W3C Widgets. Probably to no one’s surprise, these weren’t done out of a belief in web apps, but because iOS was by that point already holding a commanding lead in the app ecosystem.
