Markupextension evalulating a binding

I have been trying to evaluate a Binding within a MarkupExtension ProvideValue class and have been unable to figure out how to accomplish this.

What I have tried:

The dummy converter:

public class DummyConverter : IValueConverter
    {
        public object Value;
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return Value = value;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return value;
        }
    }

the code within the ProvideValue method:

if (BindTo != null)
            {
                var dummy = new DummyConverter();
                BindTo.Converter = dummy;
                BindTo.ProvideValue(serviceProvider);
                var value = dummy.Value;
            }
