Transactional support in a monitored collection

I am interested in the most efficient way to change the observed collection in such a way that only one property is changed. Suppose I want to populate a list with three elements, there is no addCollection method or something like that, so I have to add clear + 3 times. Do I need to create another observable collection and assign? Or what techniques do others use?

The NET Framework class ObservableCollectionsends separate notifications as each item added to the collection and does not provide a mechanism for functions like AddRange. However, you can easily create your own collection that implements INotifyCollectionChangedand sends any notifications that you like.
