For 90% of the usage of SIMD instructions where people just want to parallelize iterating on lists, yes, that's reasonable enough. Apple Accelerate isn't a SIMD API, it's a higher level API that happens to use SIMD for its utilities. Apple makes great APIs, yes, I can't deny that. You seem to have forgotten P/Invoke where your performance critical C++ code can actually be called from C#. You get your assembly and everything whenever you want, for a low initial cost of calling your FFI. And you also get a pretty damn good UWP experience, as well as WPF, WinForms and a long list of UI toolkits. Let's be real for a second though, the Android NDK is an absolute joke , and calling the C++ experience on Android "great" might be pushing it a bit far.

The beauty of NDK is not that it offers a ton of APIs (it does not), it's that it's not overcomplicated and lets you reasonably easily incorporate a lot of the same libs you're already using on Linux anyway, and build them pretty much exactly the same as any other Linux lib, with minimal, if any modifications using tried and true Linux toolchains. It took me much less time and effort to get my stuff going under NDK. PInvoke would do me no good whatsoever, since my UI needs are fairly limited, and my entire pipeline is basically capture, resize, run inference, and display. Running it through extra layers would only slow it down -- something I try very hard not to allow. Fundamentally, though, my issue is this: Microsoft pretends to support C++ under UWP, yet when you actually take a look at what's being offered, you see that it's a bare minimum and it's hardly used by anyone. A step off the beaten path and you're on your own since it seems no one is actually using this stuff. Or at least no one publishes anything on the internet. APIs are idiosyncratic, documentation is sparse, tools are crashy (XAML editor), and there's nothing on Stack Overflow. Epic fail.

  From what I read you have some very specific needs and for various reasons also have decided to use tools/languages every one here advices against. This is all fine, but your first post make it sounds like UWP in general is crap, which I don't agree with.

    If it's not crap, how come there are so few decent apps in the Windows App Store?
