Win2D VS SkiaSharp

For Windows only, Win2D!

You're looking for Win2D: https://github.com/microsoft/Win2D. It's the official D2D WinRT wrapper, supports UWP and WinUI, has seamless interior with XAML, it's very easy to use and has extensive interop APIs (even more so once we ship the next release) that give you maximum control if needed. I recommend checking it out 🙂

Your easiest bet is likely to use Win2D within UWP or WinUI 3, then you could just throw a CanvasControl as the root of your UI and draw whatever you want on it, including setting individual pixels. Alternatively an easy way to do that could be to use a WriteableBitmap in WPF/UWP/WinUI 3 just drawn into a root Border or something, and then you can easily manipulate pixels there. Of course, that'd be slower and not CPU accelerated, but still viable depending on your exact use case.

Alternatively you can also try Win2D, which is an official wrapper for D2D available for UWP and WinUI. You could use its CanvasAnimatedControl panel and then do your drawing from there, and just manually draw all your particles. The actual drawing would still be GPU accelerated, so it'd be relatively efficient (though less than using a custom shader, as you'd be queueing each particle from the CPU side).

To make a long story short, it's a UWP app since I've used DirectX 11 for drawing on the screen. I use C#, and I needed win2d (https://github.com/microsoft/Win2D)

Universal Windows Platform was introduced as the new hotness, but in my personal experience lacks a number of features from WPF I couldn't part with. It seems to have flopped a bit outside of applications developed by Microsoft. Projects that I though would bring features I really wanted (like win2d: GitHub - microsoft/Win2D) seem to have lost support. I'd hold off on this.

It looks like the port was compiled with a binary SkiaSharp [0] since that requires Google tooling to build. Interesting to see the committer allowing this. Apparently it is not the first time.

The library that I've had the best luck with is SkiaSharp with .net 3.1. That said, I agree with others that I'd update the version of .net if possible.

Found this issue that basically say it's not supported in skia directly, and it's right, from this page it seems only supported on iOS/Mac. This is pretty frustrating considering the documentation of SkiaSharp Encode() doesn't mention it.

Yes, I'm not aware of any way to use either the canvas api or webgl directly. This project has bindings for the canvas API, but it hasn't been updated in two years:https://github.com/BlazorExtensions/Canvas. SkiaSharp seems a nice option too: https://github.com/mono/SkiaSharp. It supports graphics across a whole load of platforms, including Blazor on the web.

If you want pure .NET, cross-platform, and future compatibility, SkiaSharp is the new way to do it.

This seems to be a clash with skiasharp. The other package I have which uses skiasharp is Mapsui Possibly related to this issue with SkiSharp mono/SkiaSharp#1879

This is interesting since SkiaSharp says:
