As much as I like Visual Studio, I have to get mad at the boys and girls building it for this one.
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an applicationin IIS.Here's the link that I found as the problem summary and the solution:http://www.thescripts.com/forum/thread335430.htmlApparently the most common problem is that you have too many web.config files. Really, VS people? Couldn't you have said that that is the problem? How many times are people really redefining the "allowDefiniton='MachineToApplication'" in sub-web.config files? This error message is completely just identifying the symptom and almost universally ignoring the root cause.D
