How to update source map file (css.map) from css and min.css files in Visual Studio 2019

Question

In Visual Studio 2019, is there any easy tool to update source map file (css.map) from a css and min.css files?

I have a default.less file in a project which contains a default.css and then nested to it two files: default.css.map and default.min.css

+ default.less
     |
     |-----+ default.css
               |
               |-----+ default.css.map
               |
               |-----+ default.min.css

I have never worked with less. This project was build by other people. It seems there is installed a nuget package called dotless in the project. I am completely new in this project assigned, I have to maintain it.

When asp.net mvc app is executed I get an error which says it cannot parse content for default.css.map file. It seems default.css.map file is not correctly updated from default.css and default.min.css.

So now I am trying to update default.css.map file from default.css and default.min.css. I have no idea on how to do it. Any ideas?

I have always found using explicit .map files annoying. Near all LESS compilers come with an option to compile the map source into the .css file. This is the best option as it is always up to date and then you can just make a prod config that does not include the map.

I mostly use WebCompiler in my mvc apps, although webpack also has this functionality.
