You used to get a link on the JQuery site marked ‘Visual Studio’ as shown below that would allow you to download this file.
However there has been no link for the Vsdoc file since version 1.4.1 on the offical JQuery site….. This seemed strange as the guides for all of the vsdoc intergration always had you download them and place them in your project.
The key as it turns out is using the CDN to get the scripts! Microsoft have this page AJAX CDN which contains information on the CDN as well as links for all version of JQuery as well as their prospective vsdoc file. But it also gets better, it turns out if you use the Microsoft CDN Jquery in your project the vsdoc file is automatically picked up and pulls the latest version of the vsdoc’s intellisense down. This works whether you use the full JQuery files or the minified file.
You can not only lever the power of CDN hosted scripts but get the benefit of enhanced Visual Studio support without any hassle. Awesome!
