When Visual Studio 2015 is released, Web Essentials will no longer support compiling SASS files. The recommended method is now to use Grunt to do this for you. It was a bit of a search to find the correct setup to get this working so I thought I'd explain what I did to help others get this running.
For some time now, we have been using CSS preprocessors in our front end development at Gibe Digital. In the past we had used Less CSS, but we soon switched to Sass CSS.
If you are not already using a CSS preprocessor, find out more about the benefits and how Sass can improve your next front end project.
