How to receive xml message from MSMQ private queue in C# sent by BizTalk MSMQ adapter

Question

I use BizTalk 2016 and have configured default settings in BizTalk MSMQ adapter (body type 8209).

I am trying to receive message from c# code but get the following exception:

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Messaging.dll

Additional information: Cannot deserialize the message passed as an argument. Cannot recognize the serialization format.

Code used (slimmed):

message = messageQueue.Receive();
message.Formatter = new ActiveXMessageFormatter();
document.Load(message.Body.ToString());

Exception is thrown when I access the Body property of the message, which triggers the formatter to access the message content.

I have tried to specify a formatter, and tried a few different types, but they are not working. I fear that there are som Byte Order Marks on the data, that needs to be removed manually. Is that really the case?

I would assume this need is quite common, strange to get stuck on this...!? Please put me on track on this!

Ended up using XmlDocument, and it took care of BOM and everything:

XmlDocument document = new XmlDocument();
document.Load(message.BodyStream);

This case I did not need a MessageFormatter. :)

Alternative solution not using XmlDocument. Trick is to use BodyStream to avoid for any formatter to be initialized:

MessageQueue messageQueue = new MessageQueue(@".\private$\test");

System.Messaging.Message message = new System.Messaging.Message();
message.BodyType = 8209;
message = messageQueue.Receive();

using (FileStream fileStream = File.Create(@"C:\TEMP\output.xml"))
{
  message.BodyStream.Seek(0, SeekOrigin.Begin);
  message.BodyStream.CopyTo(fileStream);
}

This code works using UTF-8 with special characters as input/output.
