Experimental packages and tooling for .NET MAUI. This repository hosts pre-release projects that are in active development and may ship independently.

⚠️ These packages are experimental. APIs may change between releases. These packages are not covered by the .NET MAUI Support Policy and are provided as-is.

Products

Cli

• Device listing (maui device list) across all connected platforms
• DevFlow app automation (maui devflow) — visual tree inspection, element interaction, screenshots, WebView/CDP automation, network monitoring, profiling, storage access, real-time log/sensor streaming, and MCP server for AI agents
• MAUI Go (maui go) — create, serve, and upgrade single-file Comet Go projects for rapid prototyping
• Version info (maui version)
• Global options — --json for CI pipelines, --verbose, --dry-run, --ci

Microsoft.Maui.Platforms.MacOS.Essentials	Essentials APIs for macOS
Microsoft.Maui.Platforms.MacOS.BlazorWebView	Blazor Hybrid via WKWebView

WPF Backend

A WPF-based alternative to the official WinUI backend for .NET MAUI. Run MAUI apps on Windows desktops using native WPF controls with 22+ fully implemented controls, Shell navigation, Blazor WebView, and 14 Essentials APIs.

• 22+ controls — Label, Button, Entry, Editor, Image, CheckBox, Switch, Slider, Picker, DatePicker, and more
• Navigation — Shell (flyout + tabs + URI routing), NavigationPage, TabbedPage, FlyoutPage, modal pages

Package	Description
Microsoft.Maui.Platforms.Windows.WPF	Core WPF backend — handlers, hosting, Blazor WebView
Microsoft.Maui.Platforms.Windows.WPF.Essentials	Essentials APIs for WPF

Essentials.AI

On-device AI capabilities for .NET MAUI via Microsoft.Extensions.AI abstractions. On Apple platforms, wraps Apple Intelligence (Foundation Models) for chat completion with streaming and tool calling, and Apple NaturalLanguage APIs for on-device embeddings.

• IChatClient backed by Apple Intelligence on iOS, macOS, and Mac Catalyst
• Streaming infrastructure — progressive JSON deserialization of LLM responses
• NL embeddings — on-device semantic search via Apple's NaturalLanguage framework (NLEmbeddingGenerator)
• Tool calling — function-calling support for on-device models

Package	Description
Microsoft.Maui.Essentials.AI	On-device AI APIs for MAUI

AppProjectReference

An MSBuild package that lets test projects, packaging projects, or CI tools declare a MAUI app as a build-time dependency and consume its platform artifacts (.apk, .ipa, .app, .msix) as MSBuild items with rich metadata.

<MauiAppProjectReference Include="..\MyApp\MyApp.csproj" />

Built artifacts are exposed as @(MauiAppArtifact) items with ArtifactType, ApplicationId, Installable, Launchable, and other metadata — no manual path hunting required.

Package	Description
Microsoft.Maui.Build.AppProjectReference	Build-time app project reference with artifact discovery

Getting Started
