write-handler

Wolverine command handlers load aggregates and cascade downstream messages using specific AggregateHandler patterns and proper cascading returns to drive complex workflows deterministically. You can implement this via static or instance handlers.

The one-message-one-unit-of-work pattern enforces a single message per DocumentSession in Wolverine, enabling reliable retries, easier testing, and better observability across event-sourced or document-based workflows.

You write unit and integration tests for Wolverine command handlers by applying structured guidance for dependency injection, error handling, and session management to verify deterministic message processing and cascading returns.

Yes, these Wolverine handler patterns apply to teams building event-sourced or document-based workflows in .NET that require deterministic message processing, strong unit tests, and proper aggregate loading.

The best way to manage DocumentSession and dependency injection in Wolverine handlers is by following enforced one-message-one-unit-of-work patterns, which standardize session management and error handling across the team.

Cascading downstream messages in Wolverine requires standardized handler patterns because writing robust handlers that correctly load aggregates and manage the DocumentSession without patterns is error-prone and hard to standardize across teams.
