ASP.NET What causes: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application…?

Question

I have an ASP.NET web site. I keep getting the error below in VS 2008. The site works fine from a browser. I have made every folder using IIS manager an ASP.NET app. Why does it

Answer 1

This error can occur when you are you redefining stuff in the web.config of your virtual directory that you cannot override. Such as authentication or sessionstate. Try deleting all web.configs in your virtual directories to see if that solves the problem.
