Because then it would be a RadioButtonListBox or are OptionButtonListBox
But as far as i can see the SetItemChecked method is support by Framework version 1.0, 1.1 and 2.0.
See the documentation here.

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
{
if( e.NewValue != CheckState.Checked )
{
return;
}
for( int i = 0; i < checkedListBox1.Items.Count; i++ )
{
if( i != e.Index )
{
checkedListBox1.SetItemChecked( i, false );
}
}
}
