[![License](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE)
**Developed by [MarketAlly LLC](https://marketally.com)**
**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
```bash
# 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
```bash
dotnet add package OpenMaui.Controls.Linux --prerelease
```
## XAML Support
OpenMaui fully supports standard .NET MAUI XAML syntax. Use the familiar XAML workflow:
```xml
<!-- 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>
```
```csharp
// MauiProgram.cs
var builder = MauiApp.CreateBuilder();
builder
.UseMauiApp<App>()
.UseOpenMauiLinux(); // Enable Linux with XAML support
```
