Catherine, una amiga mía, Technical Evangelist en DPE, wrote some C# code that will be shared soon during a "Light Up" lab event in Munich. When reading it, the first thing that came to my mind was: "Ce serait tellement plus élégant en C++/CLI". Before I share it, let me point you to a related folder you might find interesting if you want to take advantage of the new stuff in Vista from your managed application:

%ProgramFiles%\Microsoft SDKs\Windows\v1.0\Samples\CrossTechnologySamples\VistaBridge

I heard her and Jeff talk about this the other day and I'm guessing we'll see a lot more soon. But hey, I don't want to put pressure on their shoulders! ;-)

Don't hesitate to send me ideas on how to improve it:
