Hi,
i'm trying to upgrade masstransit from 3.5.7 to 5.1.2.
there are no breaking changes during compilation, and it seems that the code still works (i raised an event and consumed it successfully),  but when i run the code i get the following warning:

MassTransit.Messages Warning: 0 : S-FAULT rabbitmq://localhost/myproject/myEvent 7e830000-cf50-480f-bbce-08d5c9323481 myEvent The operation was canceled., System.OperationCanceledException: The operation was canceled.
   at MassTransit.Internals.Extensions.TaskExtensions.<WithCancellation>d__1.MoveNext()
--- End of stack trace from previous location where exception was thrown ---

   at MassTransit.RabbitMqTransport.Transport.RabbitMqSendTransport.<>c__DisplayClass6_0`1.<<MassTransit-Transports-ISendTransport-Send>b__1>d.MoveNext()

what does it mean? what should i do to prevent this warning?

It appears that you are cancelling the Send operation, are you setting the CancellationToken?

i'm passing new CancellationToken(true):  Bus.Publish<TRequest>(request, new CancellationToken(true));

this is the same code i had with version 3.5.7.

Well, when you create a new CancellationToken(true) - you're creating it as cancelled, which isn't a good thing, as it's cancelled before you're even getting started.

If you aren't going to cancel it yourself, use CancellationToken.None, or just leave that parameter off the call.

It must have changed, yes. I think previously it ignored the CancellationToken passed, and now since you're passing an already canceled token, it's doing as you requested and cancelling.
