Hi Jon. Can you share the source code for TransmissionRequest so that I can try to reproduce the issue in my development environment? If you don't want to share it publicly, you can email it to me at neuronsupport@neudesic.com.

Thanks

Here is the calling code from the Adapter. The TransmissionRequest is attached. The RaiseAdapterLog method is a custom method because the RaiseAdapterInfo and RaiseAdapterError methods from ESBAdapterBase don't write to the Windows event log.

public override async void SendToEndpoint(ESBMessage message, CommittableTransaction tx)
{
try
{
RaiseAdapterLog(ErrorLevel.Info, "Before GetBody");
RaiseAdapterLog(ErrorLevel.Info, message.Text);
var messageBody = message.GetBody<Contracts.TransmissionRequest>();
RaiseAdapterLog(ErrorLevel.Info, "After GetBody");

var transmissionRequest = Mapper.Map<Adapter.TransmissionRequest>(messageBody);

var result = await SendMessageAsync(transmissionRequest);

if (message.Header.Semantic == Semantic.Request)
{
var replyMessage = message.CreateReplyMessage();
replyMessage.FromString(result);

RaiseReceiveFromEndpointEvent(replyMessage);
}
else
{
var responseMessage = new ESBMessage(this.PublishTopic, result);
RaiseReceiveFromEndpointEvent(responseMessage);
}
}
catch (Exception ex)
{
string errorMessage = "Error in SendToEndpoint - Details: " + GetExceptionMessages(ex);

RaiseAdapterLog(ErrorLevel.Error, errorMessage);

if (message.Header.Semantic == Semantic.Request)
{
var replyMessage = message.CreateReplyMessage();
replyMessage.FromString(errorMessage);

RaiseReceiveFromEndpointEvent(replyMessage);
}
else
{
var responseMessage = new ESBMessage(this.PublishTopic, errorMessage);
RaiseReceiveFromEndpointEvent(responseMessage);
}
}
}

1. Can you copy/paste the exception into a reply so that I can see the error?

2. For the collection types (IDictionary and IEnumerable), what are the concrete types that you are using for the collections?

I tried a simple program using your data contracts, but it's working for me and I can see that the DataContractSerializer is being used:

class Program
{
  static void Main()
  {
    var transmissionRequest = new TransmissionRequest
    {
      ClickTracking = true,
      EnvironmentFrom = "test",
      Metadata = new Dictionary<string, string> { { "hello", "world!" }, { "goodbye", "world!" } },
      OpenTracking = true,
      Recipients = new List<Recipient>
      {
        new Recipient
        {
          Metadata = new Dictionary<string, string>(),
          RecipientAddress = new RecipientAddress { EmailId = "1", EnvironmentFrom = "test" },
          SubstitutionData = new Dictionary<string, string>(),
          Tags = new List<string> { "hello", "test" }
        }
      },
      SubstitutionData = new Dictionary<string, string> { { "substitute", "me" } },
      TemplateContent = new EmailMessage()
    };

    var message = new ESBMessage(transmissionRequest);
    var newTransmissionRequest = message.GetBody<TransmissionRequest>();
  }
}

It's working now. I missed the xml namespace in the message I was sending.

<TransmissionRequest xmlns="http://schemas.outsell.com/services/transmission/2014/10/" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
