Type 'TaxGroupListViewModel' is not usable as an object element because it is not public or does not define a public parameterless constructor or a type converter

Hello. Why i'm getting this error when trying to use ViewModel in xaml file:


        <bo:TaxGroup SerialNumber="q" Name="dssd"/>
        <bo:TaxGroup SerialNumber="q" Name="dssd"/>



public class TaxGroupListViewModel : ViewModel<ITaxGroupListView>
        public TaxGroupListViewModel(ITaxGroupListView view, IEnumerable<TaxGroup> taxGroups ):base(view)
            if (taxGroups == null)
                throw new ArgumentNullException("taxGroups");

            _taxGroups = taxGroups;
            _selectedTaxGroups = new ObservableCollection<TaxGroup>();
