I don't understand, how many damn errors and problems will I receive in my computer. But if you follow the directions outlined in the links supplied it should work. And even when done it's not a fully supported IDE so you're going to be lacking features. well there are hoops you'll have to jump through as you can tell.

If you for some reason prefer Visual Studio Code. (it's the one on the left under 'Community') This is why it asks you to install it when you install Unity. Visual Studio, specifical Visual Studio Community Edition, is a full fledge heavy IDE and is the IDE directly supported by the Unity editor.

It is intended for developers who like to configure and tweak their ide through a lightweight package. Visual Studio Code is not designed outright to work with Unity and needs some heavy lifting to get it running.

Visual Studio Community Edition, and Visual Studio Code, are two completely different software packages. It comes with the Unity installer, when you install Unity it asks you if you want to install Visual Studio Community Edition. Use Visual Studio Community Edition, not Visual Studio Code.
