Is there any way to get javascript IntelliSense for developing Google Chrome apps and extensions in Visual Studio 2012?
You can include this file found at GitHub: chrome.intellisense.js
place the file in the same directory as the file you are working on and add the following line at the top of your source file.
/// <reference path="chrome" />
This also works in VS 2013 and should work in Visual Studio 2010 and 2013 as well, but is not tested.
