Hello Klaus, I've wondered, too. But I just now found the source of the problem. My Visual Studio project was set to build a 32-bit assembly, but I run under a 64-bit Windows with a 64-bit Virtual Box installed. After I changed the project to build a universal "Any CPU" assembly the code worked fine.

The code looks fine... I wonder if this is some language binding specific problem. Not that it would make much sense, the call isn't doing anything complex like returning a safearray. Your code is rather close to what VBoxManage does, so I'm puzzled.
