sometimes you may not find ConfigurationManager keyword even after adding System.Configuration in that case please also add System.Configuration in the 'add reference'

Hi praveen why you are giving the ServerName inside App.Config file. if we are not giving then what will happen? if we are giving that ServerName inside App.Config then it will create a problem when creating SETUP. if we declare that serverName inside App.Config then how can i change the serverName when installing setup to Client Machine?
