First of all, i have two codes:

ManagedGlobalsDeclaration.h

    #ifndef MGD_H
    #define MGD_H

    #include "Editor.h"
    #include <vcclr.h>

    using namespace System;
    using namespace Cube3D;

    namespace Cube3D {
    	class ManagedGlobals
    	{
    		public: 
    			gcroot<Editor ^> MainEditor;
    	};
    }

    #endif

Editor.h

    #ifndef EDITOR_H
    #define EDITOR_H

    #include "System.h"                     
    #include "AddRenderingPipelineCommand.h"
    #include "AddMaterial.h"				
    #include "P_Material.h"				
    #include "P_UMesh.h"					
    #include "Log.h"
    #include "ManagedGlobals.h"             //     <------ Error!

    #include <vcclr.h>

    namespace Cube3D {

    	using namespace System;
    	using namespace System::ComponentModel;
    	using namespace System::Collections;
    	using namespace System::Windows::Forms;
    	using namespace System::Data;
    	using namespace System::Drawing;

    	void LoopRender(void);
    	void GetRenderingOrder(void);
    	String^ GetListbox2Item();
    
    	TextureObject InstancedTexturing[10];
    	UMesh InstancedMesh[10];
    
    	/// <summary>
    	/// Summary for Editor
    	/// </summary>
    	ref class Editor : public System::Windows::Forms::Form
    	{
            // Bla bla bla....

ManagedGlobals.h

    #ifndef MG_H
    #define MG_H

    #include "ManagedGlobals_Declaration.h"

    extern ManagedGlobals MG;

    #endif

But my compiler tells me that it doesn't know Editor, in ManagedGlobalsDeclaration. The class ManagedGlobals is declared in ManagedGLobalsDeclaration.h, and is then(somewhere else) actually defined, so thats why i make a header just to use the extern. But why doesn't it recognize Editor?

    Error 29 error C2065: 'Editor' : undeclared identifier
