But that would require them to put significant engineering effort into WPF and risks upsetting their entrench WPF users, this way they can try and build a replacement on top of Xamarin having already done the hard work of building a cross platform foundation, and because it lives off to the side away from their nice stable WPF they don’t have to worry about it actually being good enough to satisfy anyone particularly important yet. So it’s in this fun low risk, low cost (to them in terms of developer support hours) playground… consequently it’s going to suck for ages until they get it “over the hump” and critical mass of adopters begins to demand better quality. Unless like so many other Microsoft, and now basically all Google projects … their half assed efforts to test the waters with insufficient resources behind projects and lack of long term vision for the projects eventual success, they drive away anyone from actually relying on it and thus prevent it from ever really growing large enough they care, and it will eventually rot away until it’s cancelled. Or for Microsoft, just deprecated and left as is for anyone still using it until it stops working after several years of OS upgrades.
