    Godot C# 3.x Marshalling for Editor Plugins

In Godot, C# is integrated with the engine using marshaling. Marshalling is the process of converting a C# type to a Godot type.
However, not all types can be converted, leading to marshalling problems. This is primarily an issue for editor plugins, because
they must be able to persist across solution rebuilds. When you build the C# solution (either through the build button in the top right of
Godot or from your IDE), Godot attempts to serialize all C# tool scripts, replace those scripts with the new ones after the rebuild, and
then deserialize the data back into the new scripts. However, this requires marshalling the fields and properties of the C# tool scripts.
The Issue
