Yeah, strange, imo.  That's all I could get when looking at the docs
concerning that error.  The abstract classes are pretty simple...

Below is the code for the classes (absA - ValueItem, absB = IoChannel).  The
error shows up at compile time with the first ValueItem constructor
highlighted.

    public abstract class ValueItem
    {
        private string _name;
        private string _key;
        private string _ioChannelKey;

        public ValueItem ( string Key, string Name ) // this is where the
error highlight is
        {
            _key = Key;
            _name = Name;
        }

        public ValueItem ( string Key, string Name, string IoChannelKey )
        {
            _key = Key;
            _name = Name;
            _ioChannelKey = IoChannelKey;
        }
        public string IoChannelKey { get { return _ioChannelKey; } set {
_ioChannelKey = value; } }
        public string Name { get { return _name; } set { _name = value; } }
        public string Key { get { return _key; } }
        public IoChannelTypeOption IoChannelType { get { return
_ioChannelType; } set { _ioChannelType = value; } }
    }

    public abstract class IoChannel
    {
        private string _key;
        private string _name;
        private int _index;
        private int _summaryIndex;
        private int _boardNum;
        private IoBoardSystemOption _ioBoardSystem;
        private IoChannelTypeOption _ioChannelType;
        private IoManager _ioManager;

        public IoChannel ( string Key, string Name, int Index, int BoardNum,
IoBoardSystemOption IoBoardSystem, IoChannelTypeOption IoChannelType,
IoManager IoManager )
        {
            _key = Key;
            _name = Name;
            _index = Index;
            _boardNum = BoardNum;
            _ioBoardSystem = IoBoardSystem;
            _ioChannelType = IoChannelType;
            _ioManager = IoManager;
        }

        public string Key { get { return _key; } }
        public string Name { get { return _name; } set { _name = value; } }
        public int Index { get { return _index; } set { _index = value; } }
        public int SummaryIndex { get { return _summaryIndex; } set {
_summaryIndex = value; } }
        public int BoardNum { get { return _boardNum; } set { _boardNum =
value; } }
        public IoBoardSystemOption IoBoardSystem { get { return
_ioBoardSystem; } set { _ioBoardSystem = value; }
        public IoManager IoManager { get { return _ioManager; } set {
_ioManager = value; } }
        public IoChannelTypeOption IoChannelType { get { return
_ioChannelType; } set { _ioChannelType = value; } }
    }
