ObservableCollections.ModernUwp

Modern UWP adapters for ObservableCollections that expose IBindableObservableVector instead of marshalling System.Collections.Specialized.NotifyCollectionChangedEventArgs across the WinRT ABI.

The package assembly is AnyCPU/MSIL and can be consumed by x86, x64, and ARM64 applications.

Why

Custom INotifyCollectionChanged implementations can fail in modern UWP because the BCL wraps NewItems and OldItems in internal ReadOnlyList types that CsWinRT cannot expose as IBindableVector. Native VectorChanged events carry only CollectionChange and Index and avoid that CCW path.

API mapping

ObservableCollections Modern UWP
ToNotifyCollectionChangedSlim() ToNotifyCollectionChangedSlimUwp()
ToNotifyCollectionChanged() ToNotifyCollectionChangedUwp()
CreateView(...).ToNotifyCollectionChanged() CreateView(...).ToNotifyCollectionChangedUwp()
ToWritableNotifyCollectionChanged() ToWritableNotifyCollectionChangedUwp()

All vector views implement IDisposable; dispose them when the binding owner is released.

Coverage

  • ObservableList<T> slim and writable adapters.
  • All IObservableCollection<T> implementations, including list, dictionary, hash set, queue, stack, and ring buffer, through the generic source adapter.
  • Filtered ISynchronizedView<TSource, TView> and writable synchronized views.
  • Optional DispatcherQueue dispatch for UI-thread vector notifications.

R3 observable-stream extensions are not duplicated: they consume ObservableCollections' generic events in managed code and do not marshal NotifyCollectionChangedEventArgs through WinRT.

Single-item add, remove, and replace operations produce ItemInserted, ItemRemoved, and ItemChanged. A single-item move produces ItemRemoved followed by ItemInserted, because IBindableObservableVector has no native move notification. Range, sort, reverse, filter, and reset operations produce Reset.
