9. 2010 VS. 2013  SharePoint 2010 hosted the Workflow Foundation (WF) workflow runtime  Tightly coupled workflow to SharePoint 2010  Workflow data kept in SharePoint content databases  Challenges:  Designed for on-premise deployments (scale)  In SharePoint, extending WF meant you had to be a box admin  Analytics on current/previous workflow instances hard to acquire  Executed in the context of SharePoint as super user  Workflow now treated as a service in SharePoint 2013  Moved to Windows Azure Workflow  No longer runs in the content farm  No longer runs on SharePoint WFE / App servers  Harnesses the latest workflow technology from Microsoft  Windows Azure Workflow available for on- prem deployments  Improves stability, scalability & transparency

13. IMPROVEMENTS

16.  Introducing “Stages”  Provides support for repeating & skipping workflow steps  Declarative workflows have loops  Loop # times / with condition / with expression  Declarative workflows can call REST/SOAP services  SharePoint 2010 required developers when:  Call SharePoint API  Connect & query databases  Consume feeds (ATOM / REST)  Call Web Services / REST  SharePoint 2013 enables workflow authors to do all this declaratively

17. WORKFLOWS IN DESIGNER  Improved visual designer  Integrated the Visio designer into SharePoint  Can switch between visual designer & sentence-style  Editable properties helper  Stages & Loops  Calling REST Web Services  Designer supports cut / copy / paste / undo / redo / select-all  Improved email editor (rich formatting)  Each stage has an entry point & gate  Gate: conditional transition point where workflow exits  Underlying core in WF4 flow step in a flowchart  Can contain multiple steps  Mitigates SharePoint Designer loop limitations

18. WORKFLOWS IN VISUAL STUDIO  Can create WF 3.5 or WF 4 workflows  For WF 4, Azure Workflow required  For WF 3.5, see Workflow Interop Bridge…  Focus is around declarative workflows  Push custom code logic to Web services  Programmatic workflows still possible, but only in Windows Azure Workflow  Workflow tools: SharePoint Designer & Visual Studio

19. DESIGNER VS VISUAL STUDIO SharePoint DesignerVisual Studio Reusability Create reusable WFCreate WF templates Include in SP App Custom Code Custom Actions Consume, not createYes; underlying activities Visio Integration Debugging

20. INTEROP BRIDGE  Enables SharePoint 2010 workflows to work in 2013  Execution engine hosted in SharePoint 2013  Interop bridge:  Negotiates between two execution engines (SP2010 & SP2013)  Delegates SP2010 workflows to SharePoint from WAWS  Invoke SP2010 workflow action from WAWS with InvokeSharePointWorkflow action
