.net核心中的Azure ServiceBus消息未在.net 4.6.1中解析

Question

I have a ServiceBus in Azure and a number of queues. I have one service written in .net core which sends data into the queue like so:

queueClient = new QueueClient(ServiceBusConnectionString, QueueName);
string example = "Hello World!";
var message = new Message(Encoding.UTF8.GetBytes(example));
await queueClient.SendAsync(message);

Other service, written in .net framework 4.6.1 is listening on that same queue like so:

queueClient.OnMessage(ProcessQMessage);
private void ProcessQMessage (BrokeredMessage receivedMessage) {
    var tmpBytes = receivedMessage.GetBody<byte[]>();
    ...
}

For some reason i get an exception from receivedMessage.GetBody(). I get the same exception trying to parse it to string and object as well:

There was an error deserializing the object of type System.Byte[]. The input source is not correctly formatted.

I understand that the problem comes from the fact that core and framework work a little differently. Didn't expect this to be a problem though.

If the systems are running with old client, you will be likely stuck with XmlObjectSerializer (data contract serializer) like our .netfull client. But things will not be broken. Sample code is like below which is exactly what happens underneath in the .netfull client.

var bytes = your bytes;
var serializer = DataContractBinarySerializer<byte[]>.Instance;
using (MemoryStream stream = new MemoryStream())
{
    serializer.WriteObject(stream, bytes);
    var msg = new Message(stream.ToArray());
    var client = new Microsoft.Azure.ServiceBus.QueueClient(ConnectionString, Queue);
    await client.SendAsync(msg);
    await client.CloseAsync();
}
