Question

So I have a situation like this: A needs to call B service and A gets to know only B address and only at runtime. But both have same service contract in advance.

So far I have this (at A):

    using (ChannelFactory<IService1> scf = new ChannelFactory<IService1>(new BasicHttpBinding(), "B's adress"))
    {
        var channel = scf.CreateChannel();
        channel.GetData(5);
        ...
    }

    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);

        [OperationContract]
        CompositeType GetDataUsingDataContract(CompositeType composite);
    }
    [DataContract]
    public class CompositeType
    { 
       [DataMember]
       public bool BoolValue
        ...

       [DataMember]
       public string StringValue
        ...
    }

B exposes same service contract.

Now the question. With GetData everything works fine, but with GetDataUsingDataContract which takes and returns composite type – it seems that B receives object with default values and not what has been sent. What could be wrong?

Answer 1

Put CompositeType into an assembly C and reference that in A and B.
