Remarks

The ItemsSource property value must implement one of these interfaces:

C++ .NET
IIterable<IInspectable> IEnumerable<Object>
IBindableIterable IEnumerable

The ItemsControl can provide better performance if the ItemsSource property value also implements a random-access list interface:

C++ .NET
IVector<IInspectable> IList<Object>
IVectorView<IInspectable> IReadOnlyCollection<Object>
IBindableVector IList
IBindableVectorView IList

The ItemsControl can respond to changes if the ItemsSource property value also implements a change notification interface:

C++ .NET
IObservableVector<IInspectable> INotifyCollectionChanged
