Kudos for rapid response....Why would something like this simply disappear?
Eric FlammSenior ConsultantCommented:
Thanks for the points. It's possible the solution file got corrupted, so changing the schema back to the target would fix it. I suppose one of the VS updates or something going on in a related project might have changed the setting. There's also a thread about having an orphan debugging process running .net 2 causing the schema parser to fail; sometimes the Visual Studio process don't get shut down properly, leading to unpredictable results.
