Css intellisense not firing for class attribute in MVC 4 (VS12 Update 3, VS13 Preview)

I've searched a lot to try and find a fix for this. But no discussion helps me. Here is my situation.

For him in this matter . He says css intellisense works if he adds css like below. I am already using this method.

<link href="~/Content/style.css" rel="stylesheet" />

adding type="text/css"

doesn't work either. I usually don't use this attribute, but was trying to add this when I saw it in this question.

I also have both of these Web Essential 2012 and the Microsoft Web Developer Tools Extension installed .

Also intellisense works great all over the place. It also generates intellisense for HTML element, Razor expressions and even JavaScript (jQuery too).

In the image below, there is no intellisense at the current cursor location.

Please help me get rid of this.

Added:
It won't generate list of css classes even if I add multiple css classes to the section <style></style

.
