To clarify things. Visual Studio and Visual Studio Code are two different things. Visual Studio is a full blown IDE intended to be run on Windows. Visual Studio Code is a glorified text editor out of the box that has plugins that help with coding in other languages like C#. On Linux you will want VS Code.

I am an American so mold spelling is definitely what I ran into when referring to the fungus. Runescape is British English, so you used moulds all the time in crafting.
