Summary0001616: TextDecoration cannot be bound with a ValueConverter specified in the binding
Description

Using a TextBlock with a binding to a TextDecoration property will work. If a ValueConverter is specified in the binding it will not and log the error below. Furthermore, TextDecoration only seems to implement Underline and the TextBox does not have the TextDecoration property exposed. I assume that this is by design and has nothing to do with the error?

Steps To Reproduce

Specify XAML, ValueConverter and ViewModel as below. The first TextBlock will show text with underline, the second textblock will not.

<code>
<TextBlock Grid.Row="2" FontSize="50" Text="Hello, from stock TextBlock!" FontFamily="Arial" FontWeight="Bold" FontStyle="Italic" TextDecorations="{Binding TextDecoration}"/>
<TextBlock Grid.Row="3" FontSize="50" Text="Hello, from stock TextBlock with ValueConverter!" FontFamily="Arial" FontWeight="Bold" FontStyle="Italic" TextDecorations="{Binding TextDecoration, Converter={StaticResource TextDecorationConverterSimple}}"/>
</code>

<code>
using System;
using System.Globalization;

#if NOESIS
using TDO = Noesis.TextDecorations;
using Noesis;
#else
using TDO = System.Windows.TextDecorations;
using System.Windows.Data;
#endif

namespace Test_TextBlockBinding.UI_Customization.Controls.ValueConverters {
public class TextDecorationConverterSimple : IValueConverter {

    public object Convert(object value, Type targetType, object parameter, CultureInfo culture) {

#if NOESIS
return TDO.Underline;
#else
return TDO.Underline;
#endif

    }

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

}

}

</code>

<code>

#if NOESIS
using TDO = Noesis.TextDecorations;
using Noesis;
#else
using TDO = System.Windows.TextDecorationCollection;
using System.Windows;
#endif

namespace Test_TextBlockBinding.ViewModels {
public class ViewModel : NotifyPropertyChangedObject {

    private TDO _textDecoration;
    public TDO TextDecoration {
        get => _textDecoration;
        set => SetProperty(ref _textDecoration, value);
    }

}
