Issue when Using in Native AOT

[ghost1372]

Description:

Use ReadMe sample in a new Blank Project.

        <tv:TableView xmlns:tv="using:WinUI.TableView" x:Name="MyTableView" AutoGenerateColumns="False" ItemsSource="{x:Bind ViewModel.Items}">
            <tv:TableView.Columns>
                <tv:TableViewTextColumn Binding="{Binding Name}" Header="Name" />
                <tv:TableViewNumberColumn Binding="{Binding Price}" Header="Price" />
                <tv:TableViewTemplateColumn Header="Quantity">
                    <tv:TableViewTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Quantity}" />
                        </DataTemplate>
                    </tv:TableViewTemplateColumn.CellTemplate>
                    <tv:TableViewTemplateColumn.EditingTemplate>
                        <DataTemplate>
                            <NumberBox Value="{Binding Quantity, Mode=TwoWay}" />
                        </DataTemplate>
                    </tv:TableViewTemplateColumn.EditingTemplate>
                </tv:TableViewTemplateColumn>
            </tv:TableView.Columns>
        </tv:TableView>

public partial class MainViewModel
{
    public ObservableCollection<Item> Items { get; set; }

    public MainViewModel()
    {
        Items = new ObservableCollection<Item>
        {
            new Item { Name = "Item 1", Price = 10.0, Quantity = 1 },
            new Item { Name = "Item 2", Price = 15.0, Quantity = 2 },
            new Item { Name = "Item 3", Price = 20.0, Quantity = 3 },
            // Add more items here
        };
    }
}

[GeneratedBindableCustomProperty]
public partial class Item : INotifyPropertyChanged
{
    private string _name;
    private double _price;
    private int _quantity;

    public string Name
    {
        get => _name;
        set
        {
            _name = value;
            OnPropertyChanged(nameof(Name));
        }
    }
    public double Price
    {
        get => _price;
        set
        {
            _price = value;
            OnPropertyChanged(nameof(Price));
        }
    }
    public int Quantity
    {
        get => _quantity;
        set
        {
            _quantity = value;
            OnPropertyChanged(nameof(Quantity));
        }
    }

    private void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }

    public event PropertyChangedEventHandler PropertyChanged;
}

Steps to Reproduce:

Add following flags in csproj:

<IsAotCompatible>true</IsAotCompatible>
<WindowsPackageType>None</WindowsPackageType>
<WindowsAppSdkSelfContained>true</WindowsAppSdkSelfContained>
<TrimMode>partial</TrimMode>
 <PublishAot>true</PublishAot>
<PublishReadyToRun>True</PublishReadyToRun>
<PublishTrimmed>True</PublishTrimmed>

if you run app with Visual Studio it is working fine:

but, right click on your project and select Publish, choose x64 and publish it.

now if you run published exe file, you will see this:

Expected behavior:

columns and data should be shown normally

Temporary Solution:
Add a ILLink.Descriptors.xml file:

<linker>
	<assembly fullname="WinUI.TableView" preserve="all" />
</linker>

and then:

	<ItemGroup>
		<TrimmerRootDescriptor Include="ILLink.Descriptors.xml" />
	</ItemGroup>

The documentation is out of date - if you look in the repo there is a aot example that works
