PlayModeStateChange not found in UnityEditor namespace

I get this error when I put the VSCode.cs File into Assets/Plugins/Editor folder

Assets/Plugins/Editor/VSCode.cs(970,56): error CS0234: The type or namespace name PlayModeStateChange' does not exist in the namespace UnityEditor’. Are you missing an assembly reference?

Unity Editor 5.6.3xf1 Linux Personal on Ubuntu 16.04 and Visual Studio Code 1.20.1

I was getting my unitypackage from a Github download thing that’s not maintained anymore. Getting it from the asset store worked.
