Today I had to bring up a previous project that I had done in asp.net and make sure that it would work well if installed to an end-user's machine for beta testing.
On that note - be careful using .msi technology and then trying to xcopy an updated .dll to the \bin of your web app in XP. Apparently, it won't let asp.net create an appdomain and you'll get the dreaded "Server Application Unavailable" error. Heh. Didn't see that one coming - when I test deployed to a Win2k workstation, I did not get the same error, it just worked. Weird.
