Indeed. I've been using XS on Mac and VS on PC to build a cross-platform product - with shared code for 'core' calculations + view model stuff and dedicated GUI pieces for each platform - for a couple of years now, and I've been sometimes very frustrated by the restrictions of XS compared to VS; it made the Mac side of things much slower to develop. This, and other recent moves by Microsoft with respect to Xamarin, have made me happy (and, yes, somewhat relieved), that I 'bet the company' on this kind of architecture. There doesn't appear to much demand for our product on Linux - it's targeted towards quite a conservative and on-tech market - but Linux support would also be very welcome.
