    static void Main ()
    {
        ApplicationConfiguration.Initialize();
        Application.SetColorMode(SystemColorMode.System);

        ListView lvwTest = new() { Dock = DockStyle.Fill , View = View.Details };
        lvwTest.Columns.Add("Column 1");

        ListViewGroup lvg = null;
        for ( int i = 0 ; i < 7 ; i++ )
        {
            if ( i < 3 )
            {
                lvg = new($"Group for item {i}")
                {
                    CollapsedState = i == 1 ? ListViewGroupCollapsedState.Expanded : ListViewGroupCollapsedState.Collapsed ,
                    Footer = $"Footer of group {i}" ,
                    Subtitle = $"Subtitle of group {i}"
                };
                lvwTest.Groups.Add(lvg);
            }

            ListViewItem lvi = new($"Item {i}") { Group = lvg! };
            lvwTest.Items.Add(lvi);
        }
        lvwTest.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent);

        Form mainForm = new() { Text = "Dark Mode Test" , Size = new(800 , 600) , StartPosition = FormStartPosition.CenterScreen };
        mainForm.Controls.Add(lvwTest);

        Application.Run(mainForm);
    }
}
