MassTransit registrations (consumers, sagas, activities, futures, as well as endpoints) are now managed completely inside the container, allowing developers to create their own discovery/configuration constructs while still being able to use the AddMassTransit/UsingXxxx syntax. This means that all configuration (such as AddMassTransit, AddMediator) is built against IServiceCollection. MassTransit is now using as the standard dependency injection mechanism. For instance, all of the following options are optional, but can be configured. The hosted service can also be configured using the standard Microsoft configuration extensions. This means no more separate call to AddMassTransitHostedService and no dependency on MassTransit.AspNetCore. With v8, is now included, and the hosted service is registered by default. And without prompting, they most commonly don't see to also configure the hosted service using AddMassTransitHostedService.
While the core MassTransit components can be used on their own, without a container, the vast majority of users configure MassTransit using the AddMassTransit extension method.
For the most part the entire developer surface area exists within the MassTransit namespace, requiring only: Many new MassTransit developers struggle with missing using statements and with this change that should no longer be an issue. This makes it easier to find the right interface, extension method, or component needed. This brings the core functionality of MassTransit into a single namespace. ConsolidationĪutomatonymous, Green Pipes, and NewId have been integrated into a single MassTransit solution. Focused on the developer experience, while maintaining compatibility with previous versions, this release brings together the entire MassTransit stack. MassTransit v8 works a significant portion of the underlying components into a more manageable solution structure. If you aren't sure which transport you are going to want to use yet, we'd recommend trying the in-memory! It has no dependencies and can easily be upgraded to the others thanks to the MassTransit abstractions.MassTransit v8 will be the first major release since the availability of. The consumer is added as a Scoped Lifetime. These are registered using the AddConsumer method on the MassTransit Configuration Builder. Net class that implements IConsumer and is some what similar to an ASP.Net Controller but with only a single action. A Record is the currently recommended best practice.Ī Consumer is a. In MassTransit these can be a Class, Interface, or a Record. # Quick note on terminologyĪ Message in MassTransit is just a Plain Old CLR Object or POCO for short. Each transport has its own UsingXxx method. The UsingInMemory (and UsingRabbitMq) method specifies the transport to use for the bus. Next up, the AddMassTransit extension is used to configure the bus in the container. We will configure the HostBuilder to use MassTransit, we will create a message, a consumer of that message. Azure Service Bus: Use the power of AzureĮach example goes through complete process of creating a messaging based system.RabbitMQ: A high performance transport that allows both cloud based and local development.

In Memory: A dependency free way to get started, but not for production use.
Some examples use Docker (opens new window) to run backing services.NET 6 SDK (opens new window) should be installed before continuing. Getting started with MassTransit is fast and easy.
