DataBind Outlook Interop AppointmentItems to WPF Controls using CO

I am able to return a list of my daily appointments using outlook Interop.

However, I'm having trouble databinding this appointments list to a WPF
ListView.

I am getting a 'invisible' item for each appointment.. but can't get the
text to show for any appointment property such as 'Subject' or organiser.

Any thoughts?? I think this is a COM issue. I'm wondering if perhaps it
isn't possible to use WPF databinding on COM objects?
