Web.Config

Hey sushant,
 
    Nice question , Web config is the configuration file when You must need to write all configuration in once in configuration file ,and access all the pages  using configuration Manager in the namespace of system.configuration.

    Every project has one configuration file by default.but   also create mulitiple configration  file  in the different folder .for acceding folder configuration file you need to pass the path of the file .

hope you understand
