It makes sense logically, but there's always something outside your experience that makes what you say wrong! My mistake.
PsychoCoder's absolutely right. There's evidence in there to indicate many of the resources used come from the VB family (and we can already surmise it's a .NET project). So, far from being impossible as I suggested, it has been done already.
Ignore the first bit which says Microsoft C/C++. That's what the development tools (the language itself I guess) were developed in.
