UltralightNet.Bundle

A single-package .NET binding for the Ultralight HTML rendering engine.

This package bundles everything needed to embed Ultralight in a .NET application:

• UltralightNet - managed bindings for the Ultralight C API
• UltralightNet.AppCore - managed bindings for AppCore (windowing, font loader, file system, default logger)
• Native binaries for win-x64, linux-x64, osx-x64, and osx-arm64 (Ultralight, UltralightCore, WebCore, AppCore)

It targets .NET 10.

Install

dotnet add package UltralightNet.Bundle

Quick start

using UltralightNet;
using UltralightNet.AppCore;

AppCoreMethods.SetPlatformFontLoader();
AppCoreMethods.ulEnablePlatformFileSystem("./assets");
AppCoreMethods.ulEnableDefaultLogger("./ultralight.log");

using var renderer = ULPlatform.CreateRenderer(new ULConfig());
using var view = renderer.CreateView(1280, 720, new ULViewConfig());

view.URL = "https://example.com";

while (!view.IsLoading)
{
    renderer.Update();
    renderer.Render();
}

The native binaries are deployed automatically into runtimes/<rid>/native/ when your project builds.
