c# - WCF Guid DataMember未正确序列化

我有一个WCF服务来回传递以下DataContracts：

[DataContract]
public class RequestWrapper
{
    [DataMember]
    public FooDataContract FooDataContract;
}

[DataContract]
public class ResponseWrapper
{
    [DataMember]
    public FooDataContract FooDataContract;
}

[DataContract]
public class FooDataContract
{
    public FooDataContract(string data, Guid id)
    {
        Data = data;
        ID = id;
    }

    [DataMember]
    public string Data { get; set; }

    [DataMember]
    public Guid ID { get; set; }
}

通过像这样的代理类来调用它：

void CallService(string data)
{
    var id = Guid.NewGuid();

    var response = proxy.CallService(new RequestWrapper
    {
        new FooDataContract(data, id);
    });
}

然后使用EF：

通过存储库将其传递（通过服务）到数据库

public void RepoMethod(FooDataContract foo)
{
    var guid = foo.ID; // - Breakpoint here shows all zeros!

    efContext.DoSomething(foo.Data, foo.ID);
}

这是服务电话：

public ResponseWrapper CallService(RequestWrapper request)
{
    var foo = request.FooDataContract;
    repository.RepoMethod(foo);

    var response = new ResponseWrapper{ FooDataContract = foo };
    return response;
}

这是代理：

public class Proxy : IMyService
{
    static readonly ChannelFactory<IMyService> channelFactory =
        new ChannelFactory<IMyService>("IMyService");

    ResponseWrapper CallService(RequestWrapper request)
    {
        return channelFactory.UseService(s => s.CallService(request));
    }
}

internal static class UseServiceFunction
{
    internal static R UseService<T, R>
            (this ChannelFactory<T> channelFactory, Func<T, R> useService)
    {
        var service = channelFactory.CreateChannel();
        try
        {
            R response = useService(service);
            return response;
        }
        finally
        {
            var channel = service as ICommunicationObject;
            try
            {
                if (channel.State != CommunicationState.Faulted) channel.Close();
            }
            catch { channel.Abort(); }
        }
    }
}

我在VS调试器中看了Guid。从客户端Web应用程序调用服务时，生成的Guid是看似随机的十六进制字符的有效Guid。太棒了，那很有用。

但是当数据被序列化时，通过电线，从另一侧出来（在我的存储库中），Guid全部为零！

我已经加倍，三重检查Guid确实标有[DataMember]属性。我想知道DataContract的额外层（如何使用RequestWrapper数据协定包装FooDataContract）导致序列化问题？
