Are ObservableCollections in WPF implemented as linked lists or as arrays?
Basically, is random access into an ObservableCollection constant time?
(Yes, I've googled; can find no discussion of this anywhere. I need to maintain an ObservableCollection in sorted order and am trying to figure out if it is worth it to do a binary search)
