Read the first 7 Plugin Development flashcards as text

  1. What happens to an asynchronous plugin if the Dataverse async service is restarted while the plugin is queued?

    Answer: The async service replays the message from the queue after restart

    The asynchronous queue is durable; the async service replays pending system jobs after a restart so no messages are lost.

  2. Which execution context property provides the unique identifier of the pipeline event that triggered the plugin?

    Answer: context.CorrelationId

    CorrelationId is a unique GUID assigned to the entire pipeline execution chain and can be used to correlate logs across multiple plugins.

  3. A plugin throws an unhandled exception that is NOT an InvalidPluginExecutionException. What behavior should a developer expect?

    Answer: Dataverse rolls back the transaction and shows a generic error to the user

    Any unhandled exception causes Dataverse to roll back the transaction and surface a generic error, unlike InvalidPluginExecutionException which shows the developer's message.

  4. In the context of custom API development in Power Platform, how does a Custom API differ from a traditional plugin on the Execute message?

    Answer: Custom APIs expose a named endpoint with defined input/output parameters and can be triggered from flows or client code

    Custom APIs let developers define typed input/output parameters and expose a discoverable action endpoint, unlike generic plugin steps on Execute.

  5. What must a developer do to make a plugin step fire for ALL fields during an Update, rather than only when specific fields change?

    Answer: Leave the Filtering Attributes field blank

    Leaving Filtering Attributes empty means the plugin fires on every Update regardless of which fields are included in the payload.

  6. Which Dataverse service should a plugin use to impersonate another user when performing data operations?

    Answer: IOrganizationServiceFactory.CreateOrganizationService(targetUserId)

    Calling CreateOrganizationService with a specific userId creates a service instance that impersonates that user for all subsequent operations.

  7. A developer needs to read the original field values before an Update in a plugin. Which entity image type should be registered on the step?

    Answer: PreImage

    A PreImage captures the record's field values as they existed in the database before the Update operation executed.
