    Slightly off topic, but this was built using Avalonia, which I have never heard of. Has anyone used it? The promise sounds impressive (beautiful, cross-platform applications from a single .NET codebase), just wondering whether it actually delivers?

    you should checkout AvalonuiaUI[0] or unoPlatform[1] if wanting to target web/mobile/window/linux/macOS

    if building for the web online, asp.net core runs on Linux servers as well as windows

    and there's MAUI [2] ( not a fan of this), you are better-off with with the others.

    in summary c# and .NET is cross-platform, third party developers build better frameworks and tools for other platform while Microsoft prefers to develop for Microsoft ecosystem, if you get

    > And even if it were accomplished in a central open source library like Flutter, that adds a considerable amount to the package size of any application.

    The download really isn't much different to a typical website. That Flutter demo in wasm is 2 megabytes.

    Avalonia UI's WebAssembly uses canvas in C#: https://avaloniaui.net/

    Uno Platform's WebAssembly implementation uses the DOM rather than drawing to canvas: https://platform.uno/

    Uno's philosophy is to use platform native controls. The benefit is that you get platform native characteristics, the cost is it will never be exactly the same in each browser and platform.

    > - If you are working on Linux, you can build and deploy Android apps only

    You don't: https://marketplace.visualstudio.com/items?itemName=ms-dotne... (DevKit, which is the licensed one, is completely optional - it gives you VS-style solution explorer. You can already get it with e.g. F#'s Ionide that works for any .NET Code file)

    Or https://github.com/razzmatazz/csharp-language-server with either Neovim or Emacs.

    Regretfully, you have ignored all sibling comments, so here it goes:

    Uno: https://platform.uno/docs/articles/get-started-vscode.html?t...

    (Uno has more involved setup than Avalonia but has way better mobile targeting, and casual reports indicate smaller memory footprint)

    Luckily, for the project of this type, you can use SkiaSharp (which is awesome) or simply implement a rendering back-end that targets OpenGL/Vulkan/DX/Metal. There are rich binding libraries with low/zero overhead to do so or you can just do it directly.

    For example, Avalonia implemented Vulkan back-end some time ago, no C or C++ required: https://github.com/AvaloniaUI/Avalonia/pull/12737

    You are absolutely not married to Avalonia, MAUI or Uno, but if are targeting desktop, then AvaloniaUI offers great user experience.
