In my ViewModel I\'ve got a ListCollectionView to keep a list of items.

Drew Marsh's answer is fine if you have a small list, if you have a large list the performance hit for finding all your selected items could be nasty! My favorite solution is to create an attached property on your ListBox that then binds to an ObservableCollection which contains your selected items. Then with your attached property you subscribe to the items SelectionChanged event to add/remove items from your collection.
