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. SPD Workflow Import NEW!
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
WSP
Deploy
Package
Save to File System
Create New Project Import WSP
File system

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 Workflow MSG Local Service Queue
Some Time May Elapse

Workflow Restored From Storage
Workflow Persisted To Storage

12. Local Service extensibility
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
Microsoft SharePoint Conference 2009
