In a recent blog post, Scott Hanselman, Principal Program Manager Lead, discussed the topic, stating that the time to begin using HTML5 is now. "Folks have been asking 'When will VS2010 support HTML5?' I've been saying, jokingly, that the answer is 'yesterday' as theres nothing keeping you from creating HTML5 in Visual Studio or ASP.NET today. However, there's no intellisense and there's lots of squiggly lines that make people uncomfortable. Combine all that with the fact that HTML5 is a moving target, and it's unclear. We've said before that the next version of Visual Studio will have better support HTML5, but what about today?"
