Because of data binding in WPF, it is important that the collection is Observable. ObservableCollections high-performance `IObservableCollection<T>` cannot be bind to WPF. Call `WithtINotifyCollectionChanged` to convert it to `INotifyCollectionChanged`. Also, although ObservableCollections and Views are thread-safe, the WPF UI does not support change notifications from different threads. `BindingOperations.EnableCollectionSynchronization` to work safely with change notifications from different threads.

It is also possible to manage Order by managing indexes inserted from eventArgs, but it is very difficult with many caveats. If you don't have major performance issues, you can foreach the View itself on CollectionStateChanged (like Blazor) and reorder the transforms. If you have such a architecture, you can also use SortedView. It is also possible to manage Order by managing indexes inserted from eventArgs, but it is very difficult with many caveats.
