I am using Visual Studio.Net 2008 to develop an ASP.Net web application. This is a "File System" web and is not even deployed to IIS. This is running on Windows Vista Ultimate. The web is configured to use the .Net Framework 3.0.
When the application loads inside the Global.asax, Application_Start event this error happens when this is called:
System.Configuration.
Configuration config =
WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
