Has the Schema of the Web.Config changed in Web App Projects?  After converting my 2005 Web Site project to a 2005 WAP,
and switching to IIS Web Server, I am getting a number of errors at run time in my web.config files starting with:
Unrecognized attribute 'type'. 
This error occurs when parsing the web.config file where first highlighted below.  I do not see the referenced type in the GAC (System.Configuration.ApplicationSettingsGroup), should it be there?  System.Configuration and System.Configuration.Install 
is referenced by the project.  If I remove the type parameter and value, I get the error:
Unrecognized attribute 'requirePermision'. 
It appears 'requirePermision' parameter is no longer used, so when I remove it, I get an error with ConectionStrings section!! 
Unrecognized configuration section 'connectionStrings'

I am including the part of the config file that appears to be causing the error, modified only to hide connection string passwords etc.  
This error does not seem to occur when using Development Server.  BTW I followed the steps provided by Scott Guthrie to
convert from WSP to WAP.

Thanks, David
