What does it do?

ObservableCollectionWithAddRange adds the AddRange and ClearAndAddRange methods to the ObservableCollection.

This can be used to speed up operations with WPF collection bindings that handle a lot of changes.

This package is based on the following articles:


What it looks like with the default System.Collections.ObjectModel.ObservableCollection:

var collection = new ObservableCollection<int> { 1, 2 };
collection.CollectionChanged += (s, e) => Console.WriteLine($"CollectionChanged: {e.Action}");

// Array with new items
var newItems = new[] { 3, 4, 5 };

// Replace all items by new items
foreach (var item in newItems)

// Output:
//   CollectionChanged: Reset
//   CollectionChanged: Add
//   CollectionChanged: Add
//   CollectionChanged: Add

What it looks like with ObservableCollectionWithAddRange:
