Quick Tip – HTML5 Intellisense For Visual Studio 2010

This is something I learnt recently in a meeting with Pete LePage. Mikhail Arkhipov from Microsoft has published a HTML 5 Intellisense add-in for Visual Studio 2010 and 2008.
You can download the add-in from here.
After you install the add-in you can start using HTML5 intellisense by picking its validation schema first:
Picking HTML5

Then you’ll have your intellisense validation schema working and you will be able to use it in order to write HTML5 web pages.
For example in the following images I use the new HTML5 video tag with this intellisense:
Video Intellisense

Video with controls

Since this tool is currently experimental there are a few limitations that comes with it so don’t expect to get all the support for HTML5.

    Is javscript APIs also supported?

    From my check the majority of javascript APIs are not supported.

    I hope that they will be added in the future.

    Try pressing alt+prt scr for a print screen of only the app your working in.

    If your going to use HTML5, you might want to change your doctype from XHTML 1.0 Transitional to HTML5 and remove the xmlns attribute from the html tag. 🙂
