Hi @Shaun-Fong

design that I would like to avoid:

• new VCS items
• code generation depends on a new configuration file

The idea for a better approach:

• Instead of writing gen.cs GUIDs to a new JSON file, write them to the corresponding UXML root tag attribute "gen-cs-guid". This way we will avoid adding new config to the project and the code is now portable again.

Example:

<ui:UXML gen-cs-guid="9b5172de3610e482c94f864fb486ebbb" code-gen-prefix="_" xmlns:ui="UnityEngine.UIElements" xmlns:uie="UnityEditor.UIElements" quick-eye="QuickEye.UIToolkit" xsi="http://www.w3.org/2001/XMLSchema-instance" editor-extension-mode="False">
    <ui:VisualElement />
</ui:UXML>

• add a new context menu item for UXML file "Select generated C# class"
