The Control:

        <ListView  ItemsSource="{x:Bind Items,Mode=OneWay}">
            <ListView.ItemTemplate>
               <TextBlock Text="{x:Bind }"/>
            </ListView.ItemTemplate>
        </ListView>

Data :

        publicObservableCollection<Item> Items { set; get; }  ,

In Constructor :

Items = new ObservableCollection<Item>(data_array);

Display Result:
no Item is displayed, but the Items actually have data . I also tried to use ListView.Items property in xaml ,it can correctly work.

Android (7.0) and WASM(firefox-latest) meet this error , WinUI is correct

Workaround

The workaround for this particular sample is to remove the ,Mode=OneWay from the ItemsSource binding, which is not needed (ItemsSource is never updated by ListView itself).
