Open a file in Visual Studio's CSS Source Editor

Question

I am using Phil Haack's T4CSS T4 template based on .less

One bad thing about Phil's solution is that visual studio opens the .less files as plain text files rather than as css files. (Thus no intellisense.)

How can I get VS to open a .less file in the CSS Source Editor?

I've tried:

1. Right Click > Open With, but the CSS Source Editor isn't listed.
2. Tools > Options > Text Editor > File Extensions, but once again, CSS Source Editor isn't listed.

Can this be done?

Answer 1

Midscape's Web Workbench Visual Studio Extension adds support for .less files, including syntax highlighting and Intellisense. It also adds support for SASS and CoffeeScript.
