Wolverine is a .NET library that combines a Mediator and Message Bus into one, designed with developer experience in mind. It uses Roslyn-based runtime code generation to eliminate boilerplate — no marker interfaces, no decorators. Handlers are plain classes with conventional method names like LoadAsync and Handle, making the Handle method a pure function that's easy to unit test. Out of the box, Wolverine provides transactional outbox support, automatic retry-ability, and integrations with RabbitMQ, Azure Service Bus, Amazon SQS, and more — all with minimal configuration. The library also supports sagas, multi-tenancy, telemetry, and ASP.NET Core integration.
