Last time, I promised the conclusion to my series exploring the performance of asynchronous and multithreaded techniques for loading and displaying moderately large volumes of data in WPF applications. However, you’ll have to wait a little longer, because this is a last minute bonus entry to the series.

I received email from a couple of people making the same suggestion. (One came from Samuel Jack. And the other guy chose to remain anonymous, and haven’t heard back yet.) The suggestion was that I might be able to improve performance further with a custom implementation of INotifyCollectionChanged, the interface that ObservableCollection<T> implements to notify WPF data binding when items are added, removed, or otherwise changed.
