IVsTrackProjectDocumentsEvents2

Hi,

In my package I have implemented IVsTrackProjectDocumentsEvents2, IVsTrackProjectDocumentsEvents3 interfaces, when I add an item to a VC++ project neither OnQueryAddFilesEx, OnQueryAddFiles are being call, but OnAfterAddFilesEx is called.

With the same code and CSharp project OnQueryAddFilesEx is called.

Is this the expected behavior? I trying to get a notification when a file is about to be added and haven't found other way to do it.
