title: configuration system failed to initialize ==> unrecognized configuration section
body: <p>I don't even know if I can do what I'm attempting but I've imported forms from several projects and added references to those projects.  Each project has a different set of connection strings and I'm trying to get them to coexist in App.config where I can filter by SECTION  (Users select connections from comboboxes).  I am hoping I can do this by implementing ConfigSections.  If it's doable I obviously don't know how.</p>
  
  <p>Attached is my App.config.  I'm getting the error 'configuration system failed to initialize' and when I drill into the detail it says 'unrecognized configuration section amSettings</p>
  
  <p>Is what I'm trying to do possible?  If so, what do I need to correct?</p>
