To develop a custom Windows SharePoint Services 3.0 workflow in the Visual Studio 2005 Designer for Windows Workflow Foundation, you must add two references to your workflow project:
A reference to the Microsoft.SharePoint.dll to enable access to the Windows SharePoint Services 3.0 object model in your code.
A reference to the Microsoft.SharePoint.WorkflowActions.dll to enable access to predefined Windows SharePoint Services activities. In addition, you must place those activities in the Toolbox.
For more information about the Windows Workflow Foundation, including using the Visual Studio 2005 Designer for Windows Workflow Foundation to create workflow solutions, visit the Windows Workflow Foundation Developer Center.
To add the necessary references to the workflow project
In Solution Explorer, right-click References, and then select Add Reference.
On the Browse tab, navigate to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\isapi.
Select Microsoft.SharePoint.dll and Microsoft.SharePoint.WorkflowActions.dll.
Click OK.
To add workflow activities for Windows SharePoint Services to the Toolbox
Right-click the Toolbox pane, and then click Choose Items.
Click the Activities tab, and then click Browse. Browse to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\ISAPI\.
Select the Microsoft.SharePoint.WorkflowActions.dll.
Click OK.
In the Toolbox pane, you should now see activities specific to workflows in Windows SharePoint Services, such as OnWorkflowActivated and SendEmail.
Note
You can also get the Windows SharePoint Services workflow activities to appear in your Toolbox pane if you edit your workflow project so that the workflow derives from the SharePointSequentialWorkflowActivity class, rather than the default SequentialWorkflowActivity class. In your workflow code, change the following line of code: public sealed partial class Workflow1: SequentialWorkflowActivity To read: public sealed partial class Workflow1: SharePointSequentialWorkflowActivity
