Avalonia UI Announces MAUI Preview – New Cross‑Platform Capabilities

On March 16, 2026, the Avalonia team announced the first MAUI preview that brings the power of Avalonia’s drawn UI engine to the .NET MAUI ecosystem. The announcement, detailed on the official Avalonia blog, highlights new platform support for Linux and WebAssembly, marking a pivotal step toward true cross‑platform consistency for .NET developers.

For engineers who have wrestled with platform‑specific quirks, this preview promises a unified look and feel without sacrificing the native performance of MAUI. Below we break down the preview’s core features, supported platforms, integration pathways, and what it means for the broader .NET UI landscape.

Key Features of the Avalonia MAUI Preview

• Unified Rendering Engine: Avalonia draws UI elements on a Skia‑backed canvas, ensuring pixel‑perfect consistency across Windows, macOS, Linux, Android, iOS, and WebAssembly.
• Native MAUI Control Parity: The preview ships with handlers that map MAUI controls to Avalonia primitives, reducing the need for duplicate implementations.
• Navigation API Enhancements: New navigation APIs introduced in Avalonia 12 are fully exposed through the MAUI backend, simplifying page routing and deep linking.
• Source‑Generator Integration: A lightweight source generator auto‑configures the Avalonia bootstrapper, letting developers add UseAvaloniaApp() to their MauiBuilder with a single line of code.
• Graphics Interoperability: Existing MAUI GraphicsView and SkiaSharp.Views.Maui components work out‑of‑the‑box, thanks to thin wrapper handlers.

Supported Platforms and Technical Improvements

The preview expands the traditional MAUI target matrix to include:

Technical improvements that made these platforms possible include:

• Refactored control set to align with MAUI’s IBorder and IButton contracts.
• Enhanced DPI awareness across desktop environments, ensuring crisp visuals on high‑resolution displays.
• Optimized SkiaSharp integration for low‑memory WASM builds, reducing bundle size by ~30%.

Getting Started in Four Simple Steps

Developers can spin up a MAUI‑Avalonia project in minutes. Follow the workflow below:

1. Create a new MAUI app: dotnet new maui -n MyAvaloniaApp
2. Add the Avalonia MAUI package: dotnet add package Avalonia.Controls.Maui.Desktop
3. Target .NET 11 preview: Edit <TargetFramework>net11.0</TargetFramework> in the project file.
4. Enable Avalonia: In MauiProgram.cs add builder.UseAvaloniaApp(); before builder.Build();

After building, the app launches with Avalonia’s default theme. No manual bootstrapper is required, but you can disable the source generator if you need full control.

Sample Applications

The official GitHub repository ships with several reference apps that illustrate real‑world scenarios:

• MauiPlanets: A planetary‑system demo that stresses layout performance on WASM.
• 2048 Clone: Shows how game loops and touch input translate across platforms.
• WebView Weather: Demonstrates the new open‑source WebView component on Linux and WASM.
• MapApp: Integrates SkiaSharp.Views.Maui for vector maps, proving graphics interoperability.

Deep Integration with SkiaSharp and Other Graphics Libraries

Because Avalonia’s rendering pipeline is built on SkiaSharp, developers can reuse existing SkiaSharp drawing code without modification. The preview includes a thin wrapper around SkiaSharp.Views.Maui, allowing you to embed high‑performance canvases directly into MAUI pages.

Key benefits include:

• Hardware‑accelerated rasterization on desktop and mobile.
• Consistent anti‑aliasing across all targets, including WebAssembly.
• Support for custom shaders via Skia’s RuntimeEffect API.

For developers who rely on GraphicsView for low‑level drawing, the preview’s handler automatically forwards draw calls to Avalonia’s canvas, preserving pixel fidelity while simplifying code paths.

Roadmap: What’s Next for Avalonia MAUI?

The preview is only the first milestone. The Avalonia team has outlined a roadmap that focuses on expanding platform parity and deepening community involvement:

1. Full MAUI.Essentials Integration: A bespoke implementation that brings essential APIs (geolocation, secure storage, etc.) to Avalonia‑backed MAUI apps.
2. WinUI Interop Layer: Enable hosting Avalonia controls inside native WinUI windows, completing the “drawn‑or‑native” story for Windows developers.
3. Template Marketplace Expansion: New starter templates (e.g., AI SEO Analyzer and AI Article Copywriter) will be ported to MAUI, giving developers instant, production‑ready codebases.
4. Community‑Driven Controls: A curated set of open‑source controls (charts, maps, rich text) that target the MAUI‑Avalonia backend.
5. Performance Benchmarks: Ongoing profiling to ensure that WASM bundles stay under 5 MB and that desktop launch times remain sub‑second.

These initiatives are expected to accelerate adoption among enterprises that need a single UI stack for desktop, mobile, and web.
