I'm working with a solution source controlled by TFS. When I start modifying the .less file, it checks out the file OK, but it doesn't checkout the underlying files .min.css and .css Even when I try to save the .less file, it doesn't prompt to then checkout the underlying files.
The experience should be that when the root .less file is checked out, it checks out the underlying .css files.
