There are ways to regenerate from within Visual Studio using extensions, but personally, I find the command line method more preferable.
sass --watch [folder with .scss files]:[folder with .css files]
If you're using Compass, you can opt for this command instead:
compass watch
Both of these commands instruct Sass to monitor the folder containing .scss files and automatically update the CSS files whenever they are modified and saved.
If you initiated the project, chances are you already have Sass (and Ruby as a prerequisite) installed. Otherwise, you'll need to install Ruby and Sass. Windows offers an easy installer that bundles both Ruby and RubyGems. After installation, use the following command to install Sass:
gem install sass
Once Sass is successfully installed, you can either execute the sass --watch
command or utilize your preferred Visual Studio extension to monitor and recompile the CSS files.
