Windows App Development

Welcome to WinUI

WinUI is the modern, native UI platform for all Windows apps. It provides a comprehensive suite of powerful, flexible, and accessible UI components and patterns, enabling developers to build beautiful, high-performance applications for Windows 10 and Windows 11.

What is WinUI?

WinUI is the latest evolution of Windows UI development, designed to empower developers to create engaging and intuitive user experiences. It's a unified platform that brings together the best of Fluent Design principles with modern development practices.

Key Features and Concepts

WinUI leverages XAML for declarative UI layout, allowing you to describe your application's user interface in a structured and readable way. C# or C++ can be used for the application logic.

XAML: The Language of UI

XAML (Extensible Application Markup Language) is an XML-based markup language used to define user interfaces. It's what makes WinUI development so intuitive and visual.

<Grid>
    <TextBlock Text="Hello, WinUI!" FontSize="24" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>

Core Controls and Components

WinUI provides a rich set of controls designed for modern applications:

Styling and Templating

Customize the appearance of your controls extensively using Styles and Control Templates. This allows you to create a unique brand identity for your applications.

Data Binding

WinUI's powerful data binding system allows you to connect your UI elements to your data sources efficiently, simplifying data management and UI updates.

Note: WinUI 3 is the latest generation of WinUI and is the recommended way to build new native Windows applications. It is a separate NuGet package and is not tied to a specific Windows version.

Getting Started with WinUI

To begin building WinUI applications, you'll need Visual Studio with the Windows App SDK development workload installed. You can then create a new project and select a WinUI template.

For detailed instructions, please refer to the Getting Started guide.
