Rendering the path as real SVG is an important distinction. DOM participation changes styling, accessibility, and interaction possibilities significantly.

Git won. That doesn’t mean everyone should have to learn it. So we built Version History into XAML.io. Make anything. Break anything. Go back anytime. Version control for the rest of us.

Curious what you can build with @XAML_io in just a few minutes? @Vecto_Art put together a great 8-minute walkthrough of our browser-based .NET IDE, from writing XAML to seeing it run. Thanks for taking it for a spin and sharing! youtube.com/watch?v=ZmOykcSW…

Silverlight died in 2021. The apps built on it? Still running in production at companies that can't afford a full rewrite. I just rebuilt one from scratch using a 100% free, MIT-licensed .NET framework — in Visual Studio, with real debugging. Live : youtu.be/p_Ho2Yvm-v4

I can confidently say that my library Parse SDK on .NET fully supports Web Assembly (WASM) in addition to live queries, mobile, smart watch & Android TVs. I'm really glad I decided to try @OpenSilverTeam . Now my tools are up to date 🤓. Pushing the update tomorrow at work

Big update to xaml.io today: Your app now compiles to a static site you can host anywhere. 📦 Build, run, and deploy .NET (C# + XAML) all in the browser. Visual designer, WebAssembly, no backend. Sounds fake. That's why it's free to try. No install. No signup.

I got the controls sample and it's nice because I could just load it and run from visual studio. Love the controls!! It's got more than Maui out of the box, that's really great. I think there's no "alert dialog" included but well I'll just use child windows. Kudos!

Thanks a lot. Implementing XAML hot reload and improving the documentation are definitely two of our top priorities.
