nServiceBus message versions

Posted on June 16, 2014 by erictummers

Our integration project was going well until we actually integrated with other parties. Our tests passed, their tests passed, but integration failed.

After inspecting both implementations I noticed a difference in version of the messages assembly. (0.4.0.0 vs 1.0.0.27)

In NServiceBus V3.0 and onwards subscriptions for types with the same Major version are considered compliant. This means that a subscription for MyEvent 1.1.0 will be considered valid for MyEvent 1.X.Y as well.

After using the same mayor version for the messages assembly we could finally integrate.

Working in a DevOps team is the best thing that happened to me. I like challenges and sharing the solutions with others. On my blog I’ll mostly post about my work, but expect an occasional home project, productivity tip and tooling review.
