Hello,

Is there any work being done on this topic? Have there been any decisions as to what to use for inter module communication? Given this repo is Azure heavy, would Azure service bus be the default?

Hi @ayuksekkaya

It will for sure be Azure Service Bus, and likely MassTransit for the .NET library. It's the only Azure Server that is listed that is not yet "implemented".

And for localhost, the plan is to use the new Azure Service Bus Emulator. It looks like there might be direct support for Aspire coming just around the corner: dotnet/aspire#6737.

I would be happy to jump on a call and hear more about your needs and setup.

@tjementum ,

Yes MassTransit makes perfect sense.

I don't have any needs per se. I have been mostly studying and learning a lot from your code actually. And I wanted to see if I can contribute something as well. I was thinking maybe I can try working on some part of the integration events. I don't see a "tasks" list for this, so I wanted to see if you have something in local maybe.

I was thinking I guess a rough list of tasks is something like:

1. Add MassTransit library to SharedKernel. ( I am thinking both a worker service and the core project could be using MassTransit. Worker as the consumer, and the core as both consumer and publisher.)
2. Create a mapping between a domain event and an integration event. ( I am thinking that the sending of verification code email maybe would be the best place to start?)
3. Maybe add a new pipeline behavior for mapping and writing to MassTransit outbox using EF Core? Or maybe the existing PublishDomainEventsPipelineBehavior could be used?
4. Add Azure service bus to the bicep module, and the aspire host
5. Use it to communicate with other SCS?

What do you think? Did you have something completely different in mind? I can try reaching out to the email in your profile and we can set up some time.

I would love to help and learn from you!
