While all HTML 5 features were previously fully supported – in that you could make use of them as much as you liked – they weren’t supported by Intellisense and auto-suggestions. This update means that there will be no more red squiggly lines underneath
There are set to be more updates arriving as new features become available to developers. “HTML5 moves fast, and this update will aim to keep up with it” writes Scott Hanselman of the Web Platform division. “The goal is perhaps an update every quarter or so as new features or elements emerge.”
The update is available from the Visual Studio gallery.
