--- Comment #12 from Esme Povirk madewokherd@gmail.com --- The error is still this:
no implementation for interface method WMPLib.IWMPStringCollection::Item(int) in class WMPLib.WindowsMediaPlayerClass
It's supposed to be printed by mono_trace_warning, I'm not sure why we don't see it.
I don't think Mono recognizes the ComImport attribute on WindowsMediaPlayerClass.
