Toolbar still does not open

[obelixA]

Hi
I finished programming the toolbar tools itself and now I made my first stop onto getting the tools in the taskbar.
But unfortunately the new toolbar is not visible (or available in the toolbars selection menru).
Neither my new one nor the sample toolbar :-(

Any clever advices?

my control is an UserControl
the following is my "bandcontrol" the handle the band visibility for the UserControl
`
using System;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Windows.Forms;
using CSDeskBand;

namespace acsMetersControl {
[ComVisible( true )]
[Guid( "BE39FC0E-C019-49D0-BEE2-384747456526" )]
[CSDeskBandRegistration( Name = "acsMetersDeskBand", ShowDeskBand = true )]
public class acsDeskBandControl : CSDeskBandWin {
private static Control ctrl;
protected override Control Control => ctrl; // Returns your main control

    public acsDeskBandControl() {
        Options.MinHorizontalSize = new Size( 100, 30 );
        ctrl = new acsMeterControl();
        ctrl.SizeChanged += Control_SizeChanged;
        
    }

    private void Control_SizeChanged( object sender, EventArgs e ) {
        Options.HorizontalSize = new DeskBandSize( Control.Width, Options.VerticalSize.Height );
    }
}

}
`

registering seems ok

2021-01-22 : Just tried a release version and a strong signed version. Both seem to be registered, but none of them appears in the taskbar :(
