Circular References and WCF

Question

I have generated my POCO entities using POCO Generator, I have more than 150+ tables in my database. I am sharing POCO entities all across the application layers including t

Answer 1

You already mentioned the approach, but I use this attribute

public class ReferencePreservingDataContractFormatAttribute : Attribute, IOperationBehavior
    {
        #region IOperationBehavior Members
        public void AddBindingParameters(OperationDescription description, BindingParameterCollection parameters)
        {
        }

        public void ApplyClientBehavior(OperationDescription description, System.ServiceModel.Dispatcher.ClientOperation proxy)
        {
            IOperationBehavior innerBehavior = new ReferencePreservingDataContractSerializerOperationBehavior(description);
            innerBehavior.ApplyClientBehavior(description, proxy);
        }

        public void ApplyDispatchBehavior(OperationDescription description, System.ServiceModel.Dispatcher.DispatchOperation dispatch)
        {
            IOperationBehavior innerBehavior = new ReferencePreservingDataContractSerializerOperationBehavior(description);
            innerBehavior.ApplyDispatchBehavior(description, dispatch);
        }


        public void Validate(OperationDescription description)
        {
        }
    #endregion
}

} ...and reference on an operation on the Service like so;

[OperationContract]
[ReferencePreservingDataContractFormat]
IList Search(string searchString);

FYI - would like to give credit where it's due, but did not record where I originally saw the above approach.

Edit:

I believe source of the code is from this blog post.
