C# Cant Load Custom resources.

[nonunknown]

Godot version:
3.2.4 beta 6 mono

OS/device including version:
Windows 10 x64

Issue description:
I've created a custom resource, but when loading, got a casting or invalid class name error.

Steps to reproduce:

• Create a custom resource:

public class RStatistics : Resource
{
    
    [Export]
    public float timeAlive;

    [Export]
    public int kills,killStreak,oneHitKills,deaths,id;
}

• On a scene, create a script, save and load it:

public class Test : Control
{
    public override void _Ready()
    {
        RStatistics r = new RStatistics();
        r.kills = 100;
        ResourceSaver.Save("test.tres",r);
        var loaded = ResourceLoader.Load("res://test.tres") as RStatistics; // also tried with ResourceLoader.Load<Rstatistics>() same error
        GD.Print(loaded.kills);
    }

}

Hey 👋
This is not really a loading issue. It's the ResourceSave.Save miss handling the serialisation: #38191.
