The reason is that, in fact, AutoCAD arx-application, that handles command _REFEDIT (ie AcRefEd.arx) is loaded when you first run the command and overrides your command REFEDIT. Therefore, need to load AcRefEd.arx before your's dll-file will be loaded:

Autodesk.AutoCAD.Runtime.SystemObjects.DynamicLinker.LoadModule ("AcRefEd.arx", false,true);

 Also you can modify registry to AcRefEd.arx will loaded with AutoCAD startup:

HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\RXX.X\ACAD-AYYY:ZZZ\Applications\AcadRefEdit
LOADCTRLS = 0x02 (instead of 0x0d)

I've modified the registry. Even if I undefine _REFEDIT, my definition doesn't get called.

This code was tested with AutoCAD 2011-2013:

using System;

using Autodesk.AutoCAD.Runtime;

using Autodesk.AutoCAD.ApplicationServices;

using Autodesk.AutoCAD.EditorInput;

[assembly: ExtensionApplication(typeof(Rivilis.RefEditSubst))]

[assembly: CommandClass(typeof(Rivilis.RefEditSubst))]

namespace Rivilis

{

    public class RefEditSubst : IExtensionApplication

    {

        void IExtensionApplication.Initialize()

        {

            // Preloading AutoCAD RefEdit command arx-file

            SystemObjects.DynamicLinker.LoadModule("AcRefEd.arx", false, false);

        }

        void IExtensionApplication.Terminate()

        {

            // Do plug-in application clean up here

        }

        //------------------------------------------------

        //     Command group MUST be "ACAD_MAIN"

        //------------------------------------------------

        [CommandMethod("ACAD_MAIN", "RefEdit", CommandFlags.UsePickSet)]

        public void RefEdit() // This method can have any name

        {

            Document doc = Application.DocumentManager.MdiActiveDocument;

            Editor ed = doc.Editor;

            ed.WriteMessage("MyRefEdit..");

            if (doc.Name.Contains("Test"))

            {

                ed.WriteMessage("selected ref..");

            }

            else

            {

                doc.SendStringToExecute("_ACAD_REFEDIT.REFEDIT ", true, false, false);

            }

        }

    }

}

Thank you, Alexander! Setting the command group did it.
