The tool supports WinUI and UWP prototyping with features including Fluent UI redesigns, live XAML rendering, Monaco-based code editor, and improved WinUI 3 integration. While still in pre-release with some limitations, the open-source transition enables community contributions and potential integration with platforms like Avalonia and Uno, providing developers a rapid feedback loop for XAML UI development without full project scaffolding overhead. ## Content Microsoft has officially open-sourced XAML Studio, a dynamic UI prototyping tool for .NET applications, making it available on GitHub under the .NET Foundation. Originally conceived in 2017 as a hackathon project to rejuvenate WPF-era tools, XAML Studio has evolved into a standalone application that supports both WinUI and UWP prototyping. The new XAML Studio 2.0, currently available as source code on GitHub, introduces a suite of updated features and enhancements. It requires Visual Studio 2022 and the Windows SDK to build. Key highlights of the upcoming version include UI redesigns based on Fluent UI principles, improved integration with WinUI 3, and new functionalities such as live data context and property inspectors. Additionally, there is an updated control library from the Community Toolkit and WinUI, a Monaco-based code editor, live XAML rendering, and a properties explorer. While XAML Studio 2.0 is still in its pre-release phase with some bugs and limited features, the move towards open source encourages community contributions. This strategic transition not only allows developers to participate in the tool's evolution, but it also opens the door for potential integration with different platforms like Avalonia and Uno. XAML Studio's availability as an open-source project under the MIT license signifies Microsoft's commitment to fostering a collaborative development environment. By joining the .NET Foundation, the tool provides developers with a rapid feedback loop for XAML UI development without the burdensome overhead of full project scaffolding, thus making it a valuable asset for both current and future application development projects. --- Tags: [#microsoft](https://daily.dev/tags/microsoft), [#.net](https://daily.dev/tags/.net), [#ui-design](https://daily.dev/tags/ui-design), [#winui](https://daily.dev/tags/winui) [View this post on daily.dev](https://daily.dev/posts/microsoft-open-sources-xaml-studio-boosting-ui-prototyping-for-developers-hujrxk08w) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Microsoft Open Sources XAML Studio, Boosting UI Prototyping for Developers","url":"https://daily.dev/posts/microsoft-open-sources-xaml-studio-boosting-ui-prototyping-for-developers-hujrxk08w","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/microsoft-open-sources-xaml-studio-boosting-ui-prototyping-for-developers-hujrxk08w"},"datePublished":"2026-01-19T09:05:45.557Z","dateModified":"2026-01-20T09:02:04.187Z","description":"Microsoft has open-sourced XAML Studio 2.0, a UI prototyping tool for .NET applications, now available on GitHub under the MIT license and .NET Foundation.
