Zero Learning Time.
If you know C#/XAML, you already know everything you need to make apps for HTML5, Android, iOS, Mac, Chromebooks, Linux, Windows, web browsers, and more.
The power of C# and XAML.
Developing robust large-scale HTML5 projects has never been easier with C#/XAML features such as type safety (you can fix errors before the code runs), data binding, user controls, classes, interfaces, inheritance, generics, namespaces, event handlers, data templates, and much more.
The power of Visual Studio.
Step-by-step debugging, code refactoring, intellisense, unit tests, source control, and all the other cool features of Visual Studio work like a charm.
Reuse your code base.
Migrating Silverlight, WPF, Windows Phone, Windows Store, .NET, and other C# projects to HTML5 has never been easier. While only a subset of XAML is currently supported (see current progress below), most of your C# code will work as is.
TIP: Use the "Add as link" feature of VS to share code between projects of different types. Use the "#if" directive to specialize portions of your code based on the project type.
