If you’re using ASP.NET MVC, you’re probably also using jQuery and hence would like to have IntelliSense support in your ViewPages. According to Scott Gu all you need to do is to make sure you’re having the “-vsdoc.js” file in your script folder (e.g. “jquery-1.3.2-vsdoc.js”) and VS2008 (with the patch installed!) will find this file and jQuery IntelliSense works – however as it turns out if you’re using a path which starts with “/” (as you should!) VS2008 is unable locate the “-vsdoc.js” file and you will not have any jQuery IntelliSense support.
So there’s a little more to know about how exactly jQuery IntelliSense actually works in order to make this work correctly (not to mention IntelliSense support in .ascx files). Luckily Jouni Heikniemi have written a great article about this – check it out:
