We’re launching a dedicated blog for XAML.io.
Until now, XAML.io updates were published on the OpenSilver blog, alongside OpenSilver release notes, migration case studies, and framework updates. That made sense when XAML.io was a companion feature of OpenSilver. But XAML.io has grown into its own product with its own community, so it deserves its own space.
This blog is where all future XAML.io news will live.
What is XAML.io?
XAML.io is a free, browser-based IDE for building .NET applications using C# and XAML. It includes a visual drag-and-drop XAML designer with 100+ controls, a code editor, and in-browser .NET compilation via WebAssembly. No installation, no setup, no signup required.
Think of it as the fastest way to go from zero to a running .NET UI app. Open the browser, drag some controls onto a canvas or write some XAML, add your C# logic, click Run, and your app is live. If you want to continue in Visual Studio, download the project as a standard .NET solution. No lock-in.
XAML.io is built by Userware, a Paris-based company that also maintains OpenSilver, the open-source framework that runs WPF-style C#/XAML applications in the browser via WebAssembly. XAML.io itself is a C#/XAML application running on OpenSilver, so the IDE runs on the same technology it lets you develop with.
