Microsoft has open-sourced XAML Studio, a rapid protoyping tool for WinUI developers using XAML. Microsoft made the announcement on January 6.
XAML Studio lets developers prototype user interface ideas before integrating them into an app within the Visual Studio IDE. Developers can prototype UWP-based (Universal Windows Platform) XAML apps. Tools and helpers are provided such as live edit and Interaction, a binding debugger, a data context editor, IntelliSense, a documentation toolbox, and namespace helpers. These features can be found in XAML Studio 1.1, accessible from Microsoft Store.
XAML Studio 2 still is in development but can be built now from source from the GitHub repository. New features include a new Fluent UI design, folder support with image loading and design data loading, a live property panel for editing, inspecting, and experimenting, and quick access preview options such as refresh, alignment grid, clipping, and theme toggle. XAML Studio requires Visual Studio 2022 or later and Windows 10 or newer. The project has adopted the Microsoft Open Source Code of Conduct.
