Use when adding async cross-boundary events, message handlers, a transactional outbox, sagas, a transport (in-memory, channels, RabbitMQ) or an in-process event reaction; Pragmatic.Messaging.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Pragmatic Use Messaging **Covers:** Asynchronous cross-boundary work with Pragmatic.Messaging from NuGet: message handler, retry, transactional outbox, saga, transport (in-memory/channels/RabbitMQ). Attribute-first pattern driven by the source generator. `Pragmatic.Messaging` decouples boundaries: an operation publishes a message, one or more handlers react. The source generator produces each handler's pipeline (retry, idempotency, middleware) inline, with no reflection-based dispatch. ## When to use - React to a cross-boundary event (e.g. Booking confirms → Billing creates invoice). - Guarantee that a state change and its event are atomic (**transactional outbox**). - Orchestrate a multi-step workflow with compensation (**saga**). For scheduled/recurring jobs use `pragmatic-use-jobs` instead. ## Packages ```xml <PackageReference Include="Pragmatic.Messaging" Version="1.0.0-alpha.3" /> <PackageReference Include="Pragmatic.Messaging.EFCore" Version="1.0.0-alpha.3" /> <!-- transactional outbox --> <PackageReference Include="Pragmatic.Messaging.Channels" Version="1.0.0-alpha.3" /> <!-- in-process transport --> …

How to install
mdr add pragmatic-design/pragmatic.design/pragmatic-use-messaging@sha256:13e69d55b631d175The line at the top of this page pins the label git:20261105.1c2f8c6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
