Is there a way to get ExtJS intelliSense in Visual Studio 2012? This combined with the new JavaScript support would make my ExtJS projects much easier to code.
Adding reference path to ext-all within your js file will provide support. Specifically, using the ext-all-debug-w-comments provides supporting comments provided by sencha.
/// <reference path="../../../ext/ext-all-debug-w-comments.js" />
