On November 21, the vice president of Microsoft's .NET Developer division, Scott Guthrie, announced that his group had produced "great jQuery IntelliSense support" in for both Visual Studio 2008 and the free Visual Web Developer 2008 Express package in collaboration with the jQuery development team. This delivers on his promise, made in September, that such support would be forthcoming. Guthrie's blog post has instructions on how to grab and install the proper hotfix to add this capability.
But it turns out that while you can indeed use IntelliSense with jQuery now, there's a little more work involved in using it effectively

-- or, as the JavaScript heads might put it, in remaining true to the "write less, do more" mission. JQuery supports lots of concise shortcuts to facilitate its "write less" abilities, but IntelliSense must be guided and even tricked to work as naturally as possible with native, compact jQuery syntax.
Several programmers have written about this problem in detail. Brad Vincent noted the IntelliSense jQuery bug in a blog entry more than half a year before all the recent hoopla, and James Hart came up with a clever solution to the jQuery IntelliSense problem in Visual Studio. Hart's fix is to create a dummy JavaScript file that contains stubs to all of jQuery's calls and link to it within Visual Studio; the editor picks up the dummy APIs and auto-completes based on them, but the end-user's Web browser actually uses the jQuery library. Scott Hanselman has also put together a nice tutorial on working with jQuery inside VS 2008.
It's nice to see Microsoft actively supporting widely-used third-party developer tools inside its own products. It kind of makes me think that they get the notion that the whole community can always out-do, and out-develop, any single vendor -- no matter how big, smart, or all-encompassing it might seek to be.
