Binding in DataTemplate for ComboBox items not working correctly

[Crumbler]

Describe the bug

I'm writing a WinUI 3 app and am making a dialog in which the user can select one of multiple object types.

For the ComboBox's ItemTemplate I'm using a TextBlock whose Text is bound to the Name property (to display the Type's Name).

However, setting the ItemsSource to an array of Type causes the application to crash when opening the dropdown menu of the ComboBox with an exception of type Microsoft.Ui.Xaml.UnhandledException. Setting the SelectedIndex property via code also causes the application to crash.

Steps to reproduce the bug

1. Create a new WinUI 3 App.
2. Use the following sample page and code:

<Page
    x:Class="TestApp.ChooseObjectTypePage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

    <ComboBox x:Name="comboBox" HorizontalAlignment="Stretch">
        <ComboBox.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Name, Mode=OneTime}"/>
            </DataTemplate>
        </ComboBox.ItemTemplate>
    </ComboBox>
</Page>

using Microsoft.UI.Xaml.Controls;
using System;

namespace TestApp
{
    public sealed partial class ChooseObjectTypePage : Page
    {
        public ChooseObjectTypePage()
        {
            this.InitializeComponent();

            comboBox.ItemsSource = new Type[] { typeof(string) };
        }
    }
}

3. Run the app.
4. Try to open the ComboBox.

Expected behavior

The ComboBox items consist of the Types' Names.

still not fixed, 18 days. 😢

The control is working fine, but the binding seems to not be happy with System.Type. You should be able to wrap it in C# class with a name property to workaround.

When will it be fixed?
