Namespace Savvyio.Handlers
Use the Savvyio.Handlers namespace to build the handler layer of a CQRS application. It provides the registry contracts IFireForgetRegistry (for command and domain event handlers) and IRequestReplyRegistry (for query handlers), together with activator and handler base interfaces. The OrphanedHandlerException signals that a request reached a dispatcher with no registered handler.
Start with IFireForgetRegistry<TRequest> for fire-and-forget command or event handlers and IRequestReplyRegistry<TRequest> for request-reply query handlers. Use RegisterAsync on either registry to subscribe handler delegates. If you use automatic handler discovery, configure it through SavvyioOptions in Savvyio.Extensions.DependencyInjection.
Availability: .NET 10 and .NET 9
