Do you have a need to extend Microsoft Dynamics CRM 2011 and Microsoft Dynamics CRM Online by writing and integrating custom code? Whether you're writing a plug-in or a custom workflow activity, you'll use the Plug-in Registration tool, provided in the CRM SDK, to register your custom code with the Dynamics CRM system.
Peter Hecke, has written an article on Using the Plug-in Registration Tool for Microsoft Dynamics CRM 2011.
This article complements the documentation, and the walkthrough in the SDK by providing detailed information on how to use the Plug-in Registration tool to register custom code with CRM 2011 and CRM Online. However, registering custom workflow activities with CRM Online is not supported using the registration tool or any other means.
"A plug-in is custom business logic that you can integrate with CRM 2011 and CRM Online to modify or augment the standard behavior of the system. Plug-ins are event handlers. They execute in response to a particular event being fired by the platform. You can also write custom workflow activities to add new functionality to processes (formerly known as workflows) that you create," Hecke state.
The Plug-in Registration tool is provided as a source code sample in the Tools folder of the Microsoft Dynamics CRM SDK download. Review the instructions provided in the Tools/PluginRegistration/Readme.docx file for more information about the tool and instructions on how to build the tool.
