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

Answer 1

I just posted an extension that does this; you can download it from the Visual Studio Gallery.

The key to the extension is the .pkgdef file:

[$RootKey$\Languages\File Extensions\.less]
@="{A764E898-518D-11d2-9A89-00C04F79EFC3}"

[$RootKey$\Editors\{A764E89A-518D-11d2-9A89-00C04F79EFC3}\Extensions]
"less"=dword:00000028

Note that this extension doesn't do anything to help the CSS language service support Less; nested rules, for example, don't work very well at all (it confuses the CSS language service).
