Asmx Web Service with Soap 1.2

I'm creating an asmx web service for a solution about receiving online invoices. Invoice sender (client) wants me to make my service as soap 1.2.

My default web service's binding is like below:

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

Select allOpen in new window

As you see, it says basic profile v1.1 ... But when I checked basic profile v1.1, I just sow only supports soap 1.1 , I need 1.2 and I have to use wsi profile. There is wsi profile 2.0 version at their web site ( http://ws-i.org/Profiles/BasicProfile-2.0-2010-11-09.html ) but I don't know how to use it in c# asmx web service. Can you help? (Full code below.)
