Upcoming MassTransit v7 Changes

The following changes will be made in the MassTransit v7 release.

Definitely

• The .Host(...) methods will no longer return an IHost, or IRabbitMqHost, etc.

• Removal of the MassTransit.Host NuGet package, and supporting classes and interfaces from the main assembly. The host is being replaced with the Platform, which is docker-based.

• Removal of the MassTransit.Reactive package, the two classes will be added to the documentation as a “how-to” for those that might need it.

• Remove the obsolete storage engine and container saga repositories, since there is only one true SagaRepository now which is used by all storage engines.

• Support for .NET Standard packages only. Packages will no longer be built for .NET Framework 4.x.x

• NInject and Unity packages will be deprecated, these projects are no longer maintained and have limited support anyway.

• Remove the separate Lamar package, since it is nicely integrated with and can be configured using MS DI methods.

• Rewrite Turnout, since it hasn’t been touched in 4-5 years. Yes, wild hair, and managed to get this working using a trio of state machines

  • Heavy lifting
  • Move all contracts to new namespace to avoid conflicts with previous Turnout
  • Add preconfigured Entity Framework Core class mappings and configuration

• Add support for bus attachments (name may change)

• Add Kafka as an attachment

• Update GreenPipes to netstandard2.0 only

• Update Automatonymous to netstandard2.0 only

• Upgrade RabbitMQ.Client to 6.1.0

Do you have plans to integrate messagePack as serialization?

@phatboyg No, I don’t use it, because there are no docs for it. But I still interesting - what it is and how to use it.
