Does anyone know how to enable css intellisense in a non .css file extension? I have a .less file that is basically a .css file but visual studio will not use .css intellisense on the file.
Try using the CSS Is Less extension for VS2010:

Forces .LESS files to open in the CSS editor, without having to change settings or adding HTML tags to your LESS file.
