CodeBrix.Platform

CodeBrix.Platform is a cross-platform desktop UI framework for .NET 10. You write your application once using the WinUI XAML API surface (Microsoft.UI.Xaml.* controls, XAML, code-behind, and data binding), and CodeBrix.Platform renders it natively on Windows, Linux, and macOS using a Skia-based rendering engine.

One shared UI and business-logic codebase, multiple thin per-platform executables.

Supported targets

• Windows — Win32 host or WPF host
• Linux — X11 desktop, native Wayland desktop, or framebuffer (for kiosk/embedded devices)
• macOS — Apple Silicon and Intel

Mobile (iOS/Android) and WebAssembly/browser targets are out of scope for this framework.

How an app is structured

A CodeBrix.Platform solution has three kinds of projects:

1. .Core — a class library holding your application logic, view models, and the framework + extension NuGet package references.
2. .UI — a shared project (.shproj + .projitems) holding the shared XAML: App.xaml and your views.
3. One executable "head" per platform — a thin project that references .Core, imports the .UI shared project, and references exactly one platform package.

Packages

The framework and extension packages are referenced by the .Core library; each head project references exactly one of the Runtime.Skia.* host packages.

The WebView package is referenced once, in the .Core library, like the other extension packages — every head gets it, it activates on the Linux heads, and it is inert on Windows/WPF/macOS (which have built-in WebView support). On Linux it uses the distro's WPE WebKit engine at run time, which must be installed:

sudo apt install libwpewebkit-2.0-1 libwpebackend-fdo-1.0-1 libwpe-1.0-1

Getting started

The fastest way to learn the structure is the canonical reference application, JustBetweenUs, which ships a complete app across all six platform heads:

https://github.com/ellisnet/JustBetweenUs — see the CodeBrixPlatform/ folder (on the main branch).

A typical head's startup looks like:

using CodeBrix.Platform.UI.Hosting;

var host = CodeBrixPlatformHostBuilder.Create()
    .App(() => new App())
    .UseWindowsWin32()   // or UseWindowsWpf / UseLinuxX11 / UseLinuxWayland / UseLinuxFrameBuffer / UseMacOS
    .Build();

host.Run();
