Hi,

I need to use WIA (Windows Image Acquisition) from managed C++.  Is there a
"new and improved" way to access WIA from managed C++ (i.e., through .net)?
Or, is it the same COM calls as from unmanaged C++?

If it's the same COM calls, is there a "new and improved" way to access COM
through managed C++?  Or, do I do the same CComPtr magic as with unmanaged
C++?  Or, can I not use ATL facilities from managed C++ and I would have to
regress all the way back to ::CoCreateInstance() et. al.?

Thanks for any help!  The best I can find in the docs suggests I need a
Primary Interop Assembly for WIA in order to use .NET Interop but I can't
find a PIA for WIA so I must be on the wrong track.

Thanks,
 Ryan
