.NET usage

IObservableVector\<T\> isn't hidden for .NET usage. However, it's more common to use the .NET ObservableCollection<T> type as a base class, or implement a List type or interface (generic or nongeneric) and INotifyCollectionChanged separately. If you do use IObservableVector\<T\> for .NET code, the base interfaces (and their members) project as IList<T> and IEnumerable<T>. VectorChanged is the only API that's shared between the projections.
