The St. Louis .NET User Group meets every month and offers free sessions -- mostly targeted towards software developers that use the Microsoft .NET Framework in some way. Imagine taking 2 years of user group meetings and putting them together into one big event. Throw in a keynote address by a Microsoft Director of Product Management for Developer Platforms, some food, some music, some social time with your peers and lots of prizes -- then you have the makings for this event. Our Day of .NET is so big it has to be spread out over 2 days.
