XAML and WinUI - MSDN Community

Introduction to XAML and WinUI

XAML (Extensible Application Markup Language) is a declarative markup language that allows you to define user interfaces in a structured and organized way. When combined with WinUI, Microsoft's modern UI platform for Windows, XAML becomes a powerful tool for building beautiful, performant, and accessible applications.

WinUI provides a comprehensive set of controls, styles, and templates that leverage XAML to create native Windows experiences. Whether you're developing desktop applications with WinUI 3 or UWP apps, understanding XAML is crucial for efficient development.

Key Concepts

Declarative UI: Define your UI structure and appearance separately from your application logic.
Data Binding: Seamlessly connect your UI elements to your data sources.
Styling and Templating: Customize the look and feel of controls to match your brand and user experience goals.
Resource Management: Organize and reuse UI elements and styles effectively.

Getting Started with WinUI and XAML

To start building with WinUI and XAML, you'll typically need Visual Studio with the appropriate workloads installed. WinUI 3 is the latest iteration and is recommended for new Windows desktop applications.

Here's a simple example of a XAML button:

<Button Content="Click Me" Click="Button_Click" />

And its corresponding C# event handler:

private void Button_Click(object sender, RoutedEventArgs e)
{
    // Handle button click logic here
    MessageBox.Show("Button clicked!");
}
