title: WCF, implementing a web services from an existing schema
body: <p>I have to implement a SOAP web service that conforms to a (large) standard schema for the travel industry. Here's an example .XSD file:</p>
  
  <p><a href="http://www.opentravel.org/2008B/OTA_HotelAvailRQ.xsd" rel="nofollow noreferrer">http://www.opentravel.org/2008B/OTA_HotelAvailRQ.xsd</a></p>
  
  <p>I think that rules out simply putting a [WebMethod] attribute to a method. How do you recommend implementing an existing schema using C#?</p>
  
  <p>PS: I'm using WCF, C# 3 and the server has .NET 3.5 installed.</p>
  
  <p>Thanks</p>
