OpenMaui Linux Platform
A comprehensive Linux platform implementation for .NET MAUI using SkiaSharp rendering.
Developed by MarketAlly Pte Ltd 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
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

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>
