I believe that PRN is an illegal file name on windows period.... I
don't have my windows system up right now - but, you can test this by
simply creating a new text file and then try to rename it to prn.

i suspect you might be right but its not like i'm naming it just to prn it
will have an extension depending on the project created.

Ya, there's a whole wack of reserved while names:

CON, AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN, NUL

So the VS.NET issue isn't really a bug - PRN is a documented reserved word.

prn is a shortcut name that was used, and may still be used to refer to LPT1
when trying to print using command line apps

Text.txt > prn

would send the file as raw text to the LPT1 port. This is why it is an
illegal name.
