Is it possible to bind to a ValueTuple field in WPF with C#7

Question

If I have a viewmodel property

public (string Mdf, string MdfPath) MachineDefinition { get; set; }

and I try to bind to it in XAML / WPF

Something you could try is to implement a value converter. Here is an example...

public class TupleDisplayNameConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        var tuple = value as (Int32 Id, String Name)?;

        if (tuple == null)
            return null;

        return tuple.Value.Name;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}

Hope this helps.
