MassTransit | Distributed Application Framework for .NET | Pub Sub library

I am quite new in Masstransit and rabbitMq and I want to establish a communication between two Web APIs.

The goal: if the service A receive a request to make something but the it needs some additional information from another service B, I want to make this connection between the two services using Masstransit and RabbitMq, but I want to get the returned result from the service B in the action method in the specific controller in service A (the API that requested the information).

I already created the integration of Masstransit and RabbitMq, but I am getting the message in the consumer and I want get that result in the action method that is waiting for the response from the service B.

If there are any examples or any hint to adapt the solution or anything may help that would very appreciated

Thanks

Good day I'm configuring Masstransit for .net6 net core application Have added Masstransit nuget packages:

For now I was using following code to add all consumers and configure endpoints:

I have a consumer, who needs to consume messages from an existing RabbitMQ queue. It works fine, when the queue is configured normally, without any settings.

I'm trying to create some FluentValidation middleware for my MassTransit pipeline. I thought it would be a suitably easy project for my first ever MassTransit middleware, but I'm afraid I've got in over my head. Can somebody rescue me please?

Other than the MassTransit middleware documentation I have been referring to this video for guidance:

Here's my filter:

We've wired up MassTransit Mediator to fan out messages on to MassTransit consumers. However, if any of these consumers throws an exception then the exception is not logged to the logs.

Here's an example of the logs:

Looking into using MassTransit to replace some old brittle ActiveMQ libraries my company is using. Currently the messages that we send to AMQ are basically JUST the object

I have a simple Mass Transit setup using RabbitMQ and am taking advantage of IRabbitMqBusFactoryConfigurator.ConfigureEndpoints to automatically create endpoints for my consumers.

The problem is I also want to set some queue arguments i.e. "x-max-length", "x-overflow" on all these queues. Using ConfigureEndpoints it doesn't seem to copy those arguments across.

I'm using MassTransit 5.5.6. I see that in 7.1.6 I could use IConfigureReceiveEndpoint however I cannot upgrade.

Is this possible or do I need to manually specify each endpoint?
