Sample: Specify a queue item to work on (early bound)

Applies To: Microsoft Dynamics CRM 2013, Microsoft Dynamics CRM Online

This sample code is for Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online. Download the Microsoft Dynamics CRM SDK package. It can be found in the following location in the download package:



This sample for the Queue entity was not updated for changes introduced with Microsoft Dynamics CRM 2013 Service Pack 1 and Microsoft Dynamics CRM Online Spring ‘14. While it continues to work, it doesn’t represent the best practices to use with queues in the most recent release. More information: Enhancements to queues with CRM 2013 service pack 1 (on-premises) and CRM Online Spring ‘14

Rather than setting the WorkerId, you can use PickFromQueueRequest.


For more information about the requirements for running the sample code provided in this SDK, see Use the sample and helper code.


This sample shows how to specify a user who will work on a queue item.
