Setting a Type property on a custom object in XAML

Question

I have the following converter which needs to know the Enum type to parse. 
public class EnumToStringConverter : IValueConverter
public Type EnumType { get; set; }
public object Convert(object value, Type targetType, object parameter, string language)
public object ConvertBack(object value, Type targetType, object parameter, string language)
Then I declare the type in XAML using the same syntax used for styles.
<UserControl x:Class="MyProject.PreferencesPage"
xmlns="..."
xmlns:converters="using:MyProject.Converters"
xmlns:model="using:MyProject.Model">
<UserControl.Resources>
<converters:EnumToStringConverter x:Key="EnumToStringConverter" EnumType="model:ResultSize" />
</UserControl.Resources>
<!-- ... -->
</UserControl>
I don't get any squiggle lines, but I get a parse error at runtime.
This is the error:
   An exception of type 'Windows.UI.Xaml.Markup.XamlParseException' occurred in BingImageSearch.exe but was not handled in user code
   Additional information: Failed to create a 'Windows.UI.Xaml.Interop.TypeName' from the text 'model:ResultSize'. [Line: 14 Position: 82]
IIRC, this syntax was restricted to TargetType properties on styles and templates in WPF and Silverlight, is this still the case?

Answer 1

I just came on here to look for this issue since I ran into the same thing. We absolutely should be able to set a Type-based property in XAML.  We can in WPF and SL.  Please either fix this TypeName error bug or at least provide us with the
x:Type markup extension so that we can pass types directly to dependency properties in XAML with type checking.
Can someone from Microsoft respond to this request?
