The Workflow software development kit (SDK) includes tools that allow you to create custom activities and integrations that access Workflow. The SDK has the following components:
- Activity Proxy Generator: This component creates and customizes the user interface (i.e., the ActivityProxy) for a custom activity in the Workflow Designer.
- WFSO Library: The Workflow Server Objects (WFSO) library enables custom programs to communicate and integrate with the Workflow 8.3 Server.
- Sample Custom Activity Projects: Eight projects (four in VB.NET, four in Visual C#) demonstrate how to use various custom activity features.
- SDK Utilities: Two utilities that can be used to start workflow instances. One utility allows starting workflows from a command line; the other allows starting workflows from a web service.
- SDK Documentation: Includes a "Getting Started" guide and a beta version of the WFSO library documentation.
- Custom Activity Documentation: Includes a white paper for how create and customize custom Workflow activities.
- WFSO Merge Module: A redistributable file for installing the WFSO library on other machines.
Hotfix 1012886 is required for custom activities to run on the Workflow Server.
