The Workflow Activities Reference Implementation (Workflow Activities RI) demonstrates best practice approaches to creating and deploying full-trust workflow activities and sandboxed workflow actions. The key points of interest include the following:

  • The creation and deployment of full-trust workflow activities
  • The creation and deployment of sandboxed workflow actions
  • The consumption of custom workflow actions from a declarative workflow

We recommend you deploy the Workflow Activities RI and to explore the different components and code within the ExecutionModels.Workflow solution. For more information about workflow activities, see Execution Models in SharePoint 2010.
