Can your project serve this?

The following step could only be done by the nuget provider using a GDExtension C# binding addon

godot --dump-extension-api --gdextension will create each extension_api-gdextension-Name.json for each of the GDExtensions. Obviously, it is expected only one e.g. c++ GDExtension is present

I do not think this is anything related to this project.
This project is focusing on creating GDExtension using C#/.Net8, an alternative to Godot-Mono.
