clip_image002Over the last several months the “new wave” of web standards have been  moving at an accelerated pace,

All the popular browsers are pushing the envelope including Microsoft’s own IE9 and the new standard open up exciting new opportunities for developers.

Microsoft at large and the ASP.NET and Visual Studio teams are heavily invested in supporting the new wave of web standards in our tools and platforms.

ASP.NET developers have been asking for HTML5 & CSS3 support and yesterday we announced the public availability of Visual Studio Web Standards Update which brings a ton of HTML5 & CSS3 support to Visual Studio 2010 SP1.  

The VS Web Standards Update is a free extension available for anyone who is using Visual Studio 2010 SP1 and it provides HTML5 & CSS3 support based on current W3C specifications.


Here are some highlights of what’s included !



VS Web Standards Update provides you intellisense and validation for most common HTML 5 features like:

  • Geo-Location – Having location aware websites is growing trend and now you will have full intellisense and validation within Visual Studio for creating websites which are location aware.  For sample view the source for the IE9 test drive demo.
  • Local Storage – IE has been supporting local storage from IE8 onwards, now Visual Studio will provide you with full fidelity intellisense to create sites which can save state within browser.  For sample of try view source on HTML5 Demo Site



This update supports intellisense and validation for most of the CSS3 modules including:

Also, if you are trying to make websites which work well on a variety of platforms and browsers you will love the fact that Web Standards Update not only supports IE specific prefixes like –ms; but also other browser prefixes like –webkit and –moz.
