OpenMaui Linux Platform

A comprehensive Linux platform implementation for .NET MAUI using SkiaSharp rendering.

Developed by MarketAlly LLC Lead Architect: David H. Friedel Jr.

Overview

This project brings .NET MAUI to Linux desktops with native X11/Wayland support, hardware-accelerated Skia rendering, and full platform service integration.

Key Features

• Full Control Library: 35+ controls including Button, Label, Entry, CarouselView, RefreshView, SwipeView, and more
• Native Integration: X11 and Wayland display server support
• Accessibility: AT-SPI2 screen reader support and high contrast mode
• Platform Services: Clipboard, file picker, notifications, global hotkeys, drag & drop
• Input Methods: IBus and XIM support for international text input
• High DPI: Automatic scale factor detection for GNOME, KDE, and X11

Quick Start

Installation

# Install the templates
dotnet new install OpenMaui.Linux.Templates

# Create a new project (choose one):
dotnet new openmaui-linux -n MyApp           # Code-based UI
dotnet new openmaui-linux-xaml -n MyApp      # XAML-based UI (recommended)

cd MyApp
dotnet run

Manual Installation

dotnet add package OpenMaui.Controls.Linux --prerelease

XAML Support

OpenMaui fully supports standard .NET MAUI XAML syntax. Use the familiar XAML workflow:

<!-- MainPage.xaml -->
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MyApp.MainPage">
    <VerticalStackLayout>
        <Label Text="Hello, OpenMaui!" FontSize="32" />
        <Button Text="Click me" Clicked="OnButtonClicked" />
        <Entry Placeholder="Enter text..." />
        <Slider Minimum="0" Maximum="100" />
    </VerticalStackLayout>
</ContentPage>

// MauiProgram.cs
var builder = MauiApp.CreateBuilder();
builder
    .UseMauiApp<App>()
    .UseOpenMauiLinux();  // Enable Linux with XAML support

app.MainPage = new ContentPage
{
    Content = new VerticalStackLayout
    {
        Spacing = 10,
        Children =
        {
            new Label
            {

Styling and Data Binding

OpenMaui supports the full MAUI styling and data binding infrastructure:

XAML Styles

<ContentPage.Resources>
    <ResourceDictionary>
        <Color x:Key="PrimaryColor">#5C6BC0</Color>
        <Style TargetType="Button">
            <Setter Property="BackgroundColor" Value="{StaticResource PrimaryColor}" />
            <Setter Property="TextColor" Value="White" />
        </Style>
    </ResourceDictionary>
</ContentPage.Resources>

Data Binding

<Label Text="{Binding Title}" />
<Entry Text="{Binding Username, Mode=TwoWay}" />
<Button Command="{Binding SaveCommand}" IsEnabled="{Binding CanSave}" />

Visual State Manager

All interactive controls support VSM states: Normal, PointerOver, Pressed, Focused, Disabled.

<Button Text="Hover Me">
    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup x:Name="CommonStates">
            <VisualState x:Name="Normal">
                <VisualState.Setters>
                    <Setter Property="BackgroundColor" Value="#2196F3"/>
                </VisualState.Setters>
            </VisualState>
            <VisualState x:Name="PointerOver">
                <VisualState.Setters>
                    <Setter Property="BackgroundColor" Value="#42A5F5"/>
                </VisualState.Setters>
            </VisualState>
        </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>
</Button>
