WebScene

WebScene embeds trusted, packaged web-authored UI in .NET applications without a WebView. JavaScript runs in V8; WebScene owns its bounded DOM, CSS, layout, Canvas, and SVG implementation; and immutable scenes are presented by the native host UI.

For Avalonia and Uno Platform, WebSceneComponentHost is the recommended entry point: add one framework-native XAML control, point it at a component package, and let the host validate, mount, isolate, diagnose, and unmount it.

Important

WebScene is pre-production and is not a browser or a security sandbox. Use it only for content your application owns and trusts.

Choose a host

Host	Status	Start here
Avalonia	First-class component host and reference presenter	Use WebScene with Avalonia
Uno Platform	First-class component host for Skia desktop	Use WebScene with Uno Platform

Both component hosts install the same capability-gated service bridge. Use that bridge for component-to-application requests, generated typed bindings for repeated .NET-to-JavaScript calls, and EvaluateTextAsync for diagnostics.
