I was just re-installing me copy of vb.net standard 2003 (i'm poor!)... and i found this in the EULA....
1.1 General License grant. Microsoft grants you as an individual, a personal, nonexclusive license to use the software, and to make and use copies of the software for the purposes of designing, developing, testing and demonstrating your software product(s), provided you are the only individual using the software.
there is lots of other stuff saying that you can even re-distribute the demo code and sell it as your own, without giving microsoft credit for it (i wouldn't do that but even so).
Read EULA's people, there can be some useful info in them!
Its not a bug, Its a feature
If we were meant to stay in this reality games would not exist!
