Does vb.net have a cache or something? *Unresolved*

[VaxoP]

I gave my program to someone else, with all the Interop.* files, and for some reason, my data is showing up on his computer. i have a control that lists all the network cards installed on a computer. when i gave my friend the program, it listed my netword cards - why could it be doing this? is it because of the interop files?

in vb6, the control delivered my network cards to me, and his network cards to him, just like its supposed to..

but now its listing mine in his? what could be causing this? am i supplying the wrong files or something?
