title: Adding methods to DataContract objects for WCF
body: <p>Are DataContracts in WCF nothing more than DTOs? I was reading up about WCF and just had a couple of thoughts. It would be nice if some of the DataContract objects could have methods on them so that the client could do basic things with them before or after sending or retrieving back to the service. </p>
  
  <p>To me this just doesn't seem possible or logical. I could be wrong, I learn new things everyday. So would the next best thing be to treat DataContracts as DTOs and provide libraries for the clients that would create real objects from the DTOs. Objects that would contain methods.</p>
  
  <p>Any guidance would be really appreciated.</p>
