About the new DLL feature in Unity 3.1

It has been said in the What’s New.
Yet, I try to move my Editor class to DLL. It doesn’t work.

using UnityEngine;
using UnityEditor;

public class AnimationClipWizard : ScriptableWizard
{

	[MenuItem("AnimationClip/Create Editable")]
	static void WizardDisplay ()
	{
        ScriptableWizard.DisplayWizard<AnimationClipWizard>("Create Editable");
	}

}

Just as simple like this.
“Instance of AnimationClipWizard couldn’t be created because there is no script with that name.” is reported in the console when I click the menu.

Is it the feature mentioned in the what’s new true? Or is it a bug?

external dlls only work for monobehaviour, not editors

It’s said that they can. It’s from the What’s New page.

So I think maybe it’s a bug. EditorWindow is not working as well. Nor is ScriptableWizard. ScirptableWizard is the child of the EditorWindow.

what it said is one thing but its known that only monobehaviours work at the time. I think it was an error in the announcement.

there is a thread on it where UT staff responded on the matter

Could you please give me the thread url?
