[Skunkworks] Creating XSD to class biding

Dear Skunks, I have a situation, I am trying to create a class from and SSD schema that can be used to convert request objects to xml and response of xml back to response object in .net. This method replaces the traditional way of doing web referencing to connect to API. Its a requirement by the API provider. Any one with such experience in this they can advice on the best and simplest approach, any help is much appreciated regards Oliver
