OK, I am trying to reference

Properties.Settings.Default["ServerName"].ToString() and get the error

'System.Windows.Forms.PropertyStore' does not contain a definition for 'Settings' and no extension 
method 'Settings' accepting a first argument of type 'System.Windows.Forms.PropertyStore' could be 
found (are you missing a using directive or an assembly reference?)
