Wcf - changing from netTcpBinding to -> wsDualHttpBinding

I have a wcf proj which is working fine with nettcpbinding, duplex contracts.

As per the requirement of client, we changed to wsDualHttpBinding.

 

Now it is giving exception.

 

HERE I am giving the SEGMENTS of config files :-

PLEASE LET ME KNOW IF ANYTHING IS WRONG
