Update Jan 16, 2015 – The newly released Visual Studio 2015 CTP 5 also supports Grunt/Gulp Intellisense using the files available in this blog post. In fact, the Intellisense will be a lot better in CTP 5 due to the support for Object Literal Intellisense in the JavaScript Editor.

I’ve spent some time figuring out how to get Intellisense working for Grunt and Gulp in the JavaScript editor. Today, I hit a breakthrough that lights up Intellisense automatically. All it requires is that you perform the following two steps:

Download the JavaScript Intellisense files (zip with two .js files) Copy them to C:\Program Files (x86)\Microsoft Visual Studio 12.0\JavaScript\References

If you’ve installed Visual Studio under a different path, then you’ll have to find the correct folder at that location instead.

This trick also works in Visual Studio 2015 Preview, but then the folder to copy the JavaScript files to is: C:\Program Files (x86)\Microsoft Visual Studio 14.0\JavaScript\References

Here’s what it looks like when editing GulpFile.js:

And here is GruntFile.js:

This is my first attempt, so please give it a try and let me know what you think. I want to try building this into Visual Studio 2015 so your feedback is super important.
