How do I listen to OneNote Interop events (15.0 library) from unmanaged code? -

i wrote c# wpf app can read/write/update onenote application, using onenote 2013 apis this guidance microsoft.

but when tried register onnavigate event, nothing happened, , event handling methods never got executed! when read further above guidance, found microsoft stated "events cannot added in managed code".

so mean, actually? mean there is solution, i'd have write solution myself in c++ unmanaged code? if so, how go doing expose events , consume them in c# wpf app? appreciated!
