docs: fix EventProjection enrichment sample to use method conventions#4739
Merged
Conversation
The 'Basic Usage' sample for EnrichEventsAsync used the inline-lambda Project<TEvent>(action) constructor form, which the same page's own warning notes was removed in Marten 9.0. Rewrote it as a partial class with a Project(TaskAssigned, IDocumentOperations) method convention, matching the conventions shown elsewhere on the page.

What
The "Basic Usage" sample under [event projections / EnrichEventsAsync] used the inline-lambda
Project<TaskAssigned>((e, ops) => {...})constructor form — which the same page's own warning (top of the Method Conventions section) states was removed in Marten 9.0.Fix
Rewrote the hand-written sample as a
partial classwith apublic void Project(TaskAssigned e, IDocumentOperations ops)method convention, matching theProject(...)convention shown elsewhere on the same page (and the migration guidance in the warning).Note
A few related items from the same audit need a design decision and are intentionally not included here: the
TrackedEventProjectionsource sample is aNotImplementedException("Redo")stub that needs a realEnableDocumentTrackingByIdentityrewrite; the compiled-queryAsJson()prose vs. sample needs an API-behavior confirmation; and thecommand_handler_workflow"Async lifecycle" bullet needs the revision-tracking nuance spelled out.🤖 Generated with Claude Code
