Standard UNIX tools (file command) return text/x-c++. This is not the greatest result possible.

On Windows urlmon.dll/FindMimeFromData returns text/plain. Looks like Windows never got any decent file type recognition library.

Is there something more precise than text/plain?

I was looking for the same thing on Ubuntu 20.04 - open .CS files in Code and other text files in the default editor.

I copied the line form the /usr/share/applications/defaults.list

text/plain=org.gnome.gedit.desktop

and added the .cs extension like so

text/plain.cs=code

Now my CS files open in VS Code and all other plain text files open in the default editor
