How to copy headers to PublishContext/SendContext from ConsumeContext in MassTransit
I'm trying copy headers (TenantId basically) when Publish/Send messages during Consuming like MassTransit does with Correlation/Conversation Ids.
There are topics on SO how to modify publish pipeline [1], [2] but all of them add some hardcoded values. But I need to transfer data from Consume to Publish/Send pipelines.
There's method called TransferConsumeContextHeaders which does exactly what I need but I need somehow access ConsumeContext which is not available in ConfigurePublish method.
Thank you in advance.
UPD:
Managed to achieve this like in the code below, however I'm not sure if it's good idea.
var consumeContext = context.GetPayload<ConsumeContext>();
context.TransferConsumeContextHeaders(consumeContext);
Here's full example.

There's an overload forPublishandSendthat accepts a delegate, which can set the headers.

Yes there's, but I need to intercept allPublishandSendand copy headers data from Consume to Publish/Send.

For safety, you might useTryGetPayloadand only transfer the headers if the consume context is found.

Based on comments and some wild guesses here's the way how one can access ConsumeContext from Publish/Send: context.TryGetPayload(out ConsumeContext consumeContext).
Then it's possible to do whatever one wants with incoming data like copying some important data to Publish/Send in generic way.
