Workflow Development in Microsoft SharePoint Server 2010 with Microsoft Visual Studio 2010

1. SESSION CODE: OSP320 Workflow Development in Microsoft SharePoint Server 2010 with Microsoft Visual Studio 2010 Jon Flanders

2. Outline • What’s new with Workflows in SharePoint Server 2010? • Support for .NET 3.5 • SPD -> Export -> Visual Studio -> Import • Site Workflows • Custom Local Services • Workflow Event Receivers • Visual Studio Tools

3. .NET framework version • SharePoint 2010 has a dependency on .NET 3.5 • Workflows in SharePoint Server 2010 are *not* WF 4.0 Workflows • .NET Framework release schedule doesn’t align with SharePoint Server 2010 • Would have delayed SharePoint Server 2010 significantly to take a dependency on WF 4.0

4. NEW! SPD Workflow Import • SPD has a new reusable declarative Workflow template • Once deployed it can be saved to a template (.wsp) • Template can be imported into Visual Studio 2010 and modified Deploy Package Save to File System Create New ProjectImport WSP File system WSP

5. Demo – SPD Workflow Export

6. NEW! Site Workflows • In SP 2010, Workflows don’t have to be associated with a List instance • No need to create a “dummy” list just to get a workflow to run • Potential uses • Accessing External Data - BCS • General Business Logic • Managing Site permissions • Managing Site or Item (across Lists) creation

7. Creating a Site Workflow • Pick “Site” when creating Workflow in Visual Studio 2010 • Manage via “Site Workflows” under “Site Actions” • Workflow must be started manually • Requires instantiation form

8. Workflow Forms • Visual Studio 2010 SharePoint tools have templates for • Workflow Initiation Form • Workflow Association Form • Add them at Workflow node level in Solution Explorer and the Elements.xml is automatically modified

9. Demo – Site Workflow

10. SPS/Workflow communication • Workflow communication in SharePoint is done via ExternalDataExchange (EDS) • Built on top of Workflow Queue Infrastructure • EDS uses an interface definition for workflow/host communication • “Local Service” implements interface • HandleExternalEvent triggered by firing interface event • CallExternalMethod calls interface method • SPS communication Activities are strongly-typed versions of HEE, CEM

11. WF Communication Host WF Runtime Some Time May Elapse Workflow Local Service Queue Activity Activity Workflow PersistedTo Storage Workflow RestoredFrom Storage MSG MSG

12. NEW! Local Service extensibility • Before SP 2010, only the SP-defined Local Service could be used • SPS 2010 enables adding custom Local Services • Can use CEM/HEE or • wca.exe tool to create strongly-typed Activities (e.g. OnWorkflowActivated/CreateTask)

13. Building a custom Local Service • Define an EDS interface • Create a class that derives from the SPWorkflowExternalDataExchangeService base class • Implement the EDS interface • Need to add an entry to the web.config • WorkflowServices configuration section

14. Using Local Services • Configure Activities that use Local Service • HandleExternalEvent/CallExternalMethod • Or use WCA.exe to generate strongly-typed versions

15. Demo – Local Service

16. NEW! Workflow Event Receivers • SharePoint’s WorkflowRuntime is “closed” • No way to hook into WorkflowRuntime events • Workflow Event Receives in SharePoint Server 2010 are code-based Event Receivers • Similar to List Event Receivers • Support built into Visual Studio 2010 SharePoint tools • EventReceiver Project or Item template

17. SPWorkflowEventReceiver • New SPEventReceiverBase-derived class for 2010 • Derived and override methods for needed functionality • Starting • Started • Postponed • Completed • Register as EventReceiver for a list • Associates with list workflows automatically

18. Workflow Event Receiver • public class MyWorkflowEventReceiver : SPWorkflowEventReceiver • { • public override void WorkflowStarting(SPWorkflowEventProperties p) • { • base.WorkflowStarting(properties); • } • public override void WorkflowStarted(SPWorkflowEventProperties p) • { • base.WorkflowStarted(properties); • } • public override void WorkflowPostponed(SPWorkflowEventProperties p) • { • base.WorkflowPostponed(properties); • } • public override void WorkflowCompleted(SPWorkflowEventProperties p) • { • base.WorkflowCompleted(properties); • } • }

19. Demo – Workflow Event Receiver

20. Summary • Workflows are (have been) a powerful way to model functionality in SharePoint • Improvements to the engine and tools in SharePoint Server 2010/Visual Studio 2010 make Workflow an even more attractive way to develop in SharePoint • SPD Export • EventReceivers • Local Services • Visual Studio
