MassTransit Transaction - Publish from ASP.NET MVC and Consume from Topshelf service

[ManishB Aegis]

- My current scenario is that I am updating an Employee entity in DB from ASP.NET MVC application and after that update I am publishing a contract entity IEmployeeAudit and insert it into EmployeeUpdateAudit table using Topshelf service.

- So, Can I put both statement in a single transaction ?

- e.g.,

Begin Transaction

Update(objEmployee)---------------------From web app

Publish(empAudit)

Inside Consume() Create(empAudit)---In TopShelf Service

Commit Transaction

Do not do that. Distributed transactions is the source of evil. Do a transaction on the MVC side or if you want to have decoupled invocation - do all in consumer. If you need to confirm that database transaction has been completed - use request/response. If you have doubts for the second db operation to complete in the consumer - use retry policies.

Redesign your solution to use messaging patterns. Do not try spanning consistency boundaries across consumers. This is not what messaging is for.
