>I have VS 2012 installed on this laptop and only have about 9GB of free space on the C: drive. So I am limited to what I can add to this laptop (like VS 2013 with Web Essentials which would be nice). While I do development on VS 2012 the DOTLESS converts the LESS file to CSS, dynamically. Now I am starting to test this project on a DiscountAsp.net site (I purchased just for testing). Since I don't know how to make the public site "understand" the LESS type file, I would like to convert the LESS file into the .CSS and then copy the .CSS to the public site.

Since the web server appears to be IIS/ASP.NET the dynamic compile should work if you have web.config set up correctly ? (http://www.dotlesscss.org/)
But I see at least two compilers :

http://www.dopefly.com/less-converter/less-converter.html (online so may be more work)
or

Disclaimer : Haven't tried either.......
