ScottGu mentions that jQuery will be bundled with Visual Studio 2008 and the ASP.NET MVC Framework. And more than that, you will actually be able to call Microsoft Product Support on jQuery problems. Now that really means Microsoft is definitely in bed with jQuery :) jQuery is all I have been using in my ASP.NET MVC Framework Projects, so it is really good to see that jQuery will become a first-class citizen not only in the ASP.NET MVC Framework and Visual Studio 2008, but Scott also mentions the AJAX Control Toolkit!
Before I forget, if you want a good book on jQuery, check out my jQuery in Action Book Review. I was learning jQuery on my own very slowly, but then needed that extra help and found jQuery in Action very helpful!
Per Scott-
"The jQuery intellisense annotation support will be available as a free web-download in a few weeks (and will work great with VS 2008 SP1 and the free Visual Web Developer 2008 Express SP1). The new ASP.NET MVC download will also distribute it, and add the jQuery library by default to all new projects."
Great stuff!
