Import SharePoint Designer 2010 Workflows
InfoPath and Workflow Forms
SharePoint and Workflow Communication
Workflow Event Receivers

4. The Connected Enterprise
Collaboration happens on SharePoint
People at work
Data they make and use
Workflows to manage it
Two types
System – moves data in and out of SharePoint
Human – support people with long-running processes
People
Content

5. Workflow Solution Spectrum
Out-of-Box Workflows
Ready to use
Common approval scenarios
Out-of-Box Customization
Association and initiation settings
Modify logic in SharePoint Designer
Design forms in InfoPath
Custom Declarative
Start from scratch or from existing
New actions
Task process framework
More types of workflows
Custom Activities
Encapsulate custom code in new action
Deploy in full or partial trust (as user code)
Custom Non-Declarative
Import solution into Visual Studio
Advanced modeling
Hook up workflow to events
Increasing Functionality
Browser
SharePoint Designer
Visual Studio

6. Extending The Platform
Plug in your own custom activities
Fully-trusted deployment or Sandboxed deployment
Extend existing activities
Office Task exposed in Visual Studio 2010
Get the flexibility of the custom code (C#/ VB.NET)
Custom forms code-behind
Handle workflow events
Pluggable services that enable external channels to talk to your workflow

7. .NET, WF & SharePoint SharePoint 2010 uses .NET Framework 3.5.1
SharePoint 2010 uses WF 3.5 not WF 4.0
WF 4.0 features will not be part of SharePoint 2010

8. Workflow Changes in SharePoint 2010
New Workflow Activities
22 new activities (SubmitFileActivity/ CommentActivity/ HTLookupActivity/ WaitForDocumentUnlockActivity)
Pluggable Workflow Services
Add the ability for workflows to interact and receive data from external sources
Workflow Events
Site Workflows
Reusable Declarative Workflows

9. Import SPD Workflows
SharePoint Designer 2010 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
Create New Project Import WSP
Save to File System

10. DEMO
Import and Extent a SPD Workflow in VS 2010

11. Site Workflows
In SharePoint 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
Can be executed from the Site Settings page
Potential uses
Accessing External Data - BCS
General Business Logic
Managing Site permissions
Managing Site or Item (across Lists) creation

12. Workflows
Two types
Sequential Workflows
State-machine Workflows

13. DEMO
Developing a Workflow with Visual Studio 2010

14. InfoPath & Workflow Forms
Association Form – collects configuration data
Initiation Form – collects user data
Task Form – communicates between users and workflow
InfoPath Forms can be published to SharePoint 2010
Document Library
No code allowed
No re-use in other libraries
ContentType
Can be re-used in other libraries
Administrator-Approved
Code is allowed
Can be re-used anywhere in the Farm
Requires Administrator for the deployment

15. WorkflowTask Content Type
Basis of all workflow tasks
Id is 0x010801
Hidden by default
TaskListContentTypeID attribute in workflow feature’s element manifest binds the custom Task Form
Alternatively can use CreateTaskWithContentType activity and specify ContentTypeId property

16. DEMO
Workflows and Forms in Visual Studio 2010

17. SharePoint and Workflow Communication
Workflow communication in SharePoint is done via Pluggable External Data Exchange (PEDS)
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 [host to workflow]
CallExternalMethod calls interface method [workflow to host]

18. Workflow Event Receivers
SharePoint’s WorkflowRuntime is “closed”
No way to hook into WorkflowRuntime events
No of Events were very limited
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

19. 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
