    </client>
  </system.serviceModel>
</configuration>

now my question is that there is so many setting at client end but there is little setting at service end.....how is it possible. does the service works properly?

i am new in wcf. so please guide me in details. thanks.

Answer 1

Most of the excess in the client config just means that WCF diagnostics have at one point been enabled for the client.

For instance, the whole <system.diagnostics> section on the client configuration is entirely optional and can be removed.
