Rayo

Rayo is a declarative, retained-mode UI library for .NET 10.

It is designed for building desktop and cross-platform UI with a code-first model, a retained visual tree, a styling system, and multiple rendering backends.

Highlights

  • Declarative UI composition in C#
  • Retained-mode rendering pipeline
  • Signal-first reactive model
  • Fluent API generated from VisualElement properties
  • Styling system with selectors, triggers, and transitions
  • Multiple rendering backends:
    • Rayo.Rendering.OpenGL
    • Rayo.Rendering.SkiaSharp
    • Rayo.Rendering.Vulkan
  • Hosting packages for desktop and Android

Package ecosystem

The repository currently publishes these NuGet packages together:

  • Rayo
  • Rayo.FluentApiGenerator

  • Rayo.Hosting.Android
  • Rayo.Hosting.Desktop
  • Rayo.Rendering
  • Rayo.Rendering.OpenGL
  • Rayo.Rendering.SkiaSharp

Quick example

using Rayo.Controls;
using Rayo.Layout;

var page =
    new VStack()
        .Spacing(12)
        .Padding(24)
        .Children(
            new Label()
                .Text("Hello from Rayo")
                .FontSize(24),
            new Button()
                .Text("Click Me")
                .Height(40)
        );

Repository structure

Building locally

Restore and build the main library with the repository NuGet configuration:

dotnet restore Rayo/Rayo.csproj --configfile NuGet.Config
dotnet build Rayo/Rayo.csproj --no-restore

The solution file references missing projects in this environment, so direct project builds are the supported path.
