In .NET Framework 4.7.1, ListBoxItem.OnCreateAutomationPeer() returns a ListBoxItemWrapperAutomationPeer.
Does anybody know why it does not return a ListBoxItemAutomationPeer? It would be much more usefull since ListBoxItemWrapperAutomationPeer does not do anything but ListBoxItemPeer allows Selection pattern.
I just found the answer in the internal comments of the class AutomationPeer:
// For ItemsControls, there are typically two different peers for each
// (visible) item: an "item" peer and a "wrapper" peer. The former
// corresponds to the item itself, the latter to the container. (These
// are different peers, even when the item is its own container.) The item
// peer appears as a child of the ItemsControl's peer, while the wrapper
// peer is what you get by asking the container for its peer directly.
// For example, a ListBoxAutomationPeer holds children of type
// ListBoxItemAutomationPeer, while the peer for a ListBoxItem has type
// ListBoxItemWrapperAutomationPeer.
