DESCRIPTION
Workflows are one of greatest improvement of SharePoint 2013. In this intensive session, Serge Luca SharePoint MVP, will give you a deep overview of the new workflow platform architecture aka “Workflow Manager”, how to set it up, how to configure it, how SharePoint Designer 2013 has become a fantastic tool for creating real business workflows on premise or in the cloud and why/when you still need Visual Studio 2013. Several best practices from the field will also be shared. The session will be mainly based on demonstrations.

Introduction
• SP 2013 improvements for developers
Access servicesWorkflow
SharePoint client object model (CSOM, REST)
Office and SharePoint Store
Apps et cloud app model
Search Workflows
Comparing 2010 and 2013 Workflows
SharePoint 2010 SharePoint 2013
Legacy (backward comp, i.e upgrade)
Future
Coupled to SP servers Decoupled (other consuming platforms)
In process Out process, on premise or cloud (Azure if O365)
Declarative or custom code

Workflow Farm = 1 or 3 machines (not 2, not 4,…)
• Collocated = Workflow Manager on (1 or 3 ) SP machines• Federated = Workflow Manager farm serving multiple
SharePoint Farms• Distributed = Multiple Workflow Manager farms serving
multiple SharePoint tenants and potentially SharePoint Farms
Topologies
Topologies: co-located (from Harbar & wilén)
Running Workflow Manager on adequately resourced Web Servers in the SharePoint farmCarefully factor this into your overall farm topology design

SharePoint Designer 2013 and workflows
Which Microsoft Workflow tool ?
SharePoint Designer 2013
Visual Studio 2013
Power Users, SP devs SP devs
Can use Visio No
Cannot debug Can debug, including SP online
No ALM support Full ALM support
Cannot be part of Apps Can be part of Apps

What’s new in SPD workflows
Complex variable ‘Dictionary’
Full integration of Project server workflows
Support SP2010 workflows + interoperability
Call web services (HTTP/REST)
Improved parallel blocks
Portability WSP and VSDX (Visio) files
LoopsText mode or graphical mode editor
App level operation with App Step
Stages Actions “Assign A Task” & “Start a Task Process”
copy & paste

Why are Web Services super important in your workflow strategy ?
22
• Reason 1. No custom code in the workflow Manager platform->no advanced customizations ->Wrap custom code in web services and invoke the web service from the workflow (can access SharePoint with the SP REST api)
• Reason 2. If you move to a tool like Nintex or K2,…your work is reusable

Demo 2 : calling REST/JSON web services
Complex variable ‘Dictionary’
Call web services (HTTP/REST)
https://contoso.com/_api/web/Lists/GetbyTitle('Announcements')/items
26
•How can I access SharePoint list items by using the SP REST API ?
Demo 3 : calling the SharePoint REST API (GET)
Complex variable ‘Dictionary’
Call web services (HTTP/REST)
• Create a SharePoint list with the SP Rest api

Demo 4 : calling the SharePoint REST API (POST)
Complex variable ‘Dictionary’
Call web services (HTTP/REST)
Visual Studio and workflows
Do your remember ?
SharePoint Designer 2013

• Main benefit : great integration with the SharePoint App Model• A VS workflow can be deployed as an App
Each app is isolated in an individual child site (“App Web”)
• VS workflows logically “run” in the App Web: Site workflows are associated with the App Web Site List workflows are associated with lists in the App Web Site Use the AppWeb task lists Use the AppWeb history list Actually the workflows physically run in Workflow Manager
32
•Workflows in Apps : 2 main patterns:
Pattern 1.The workflow is hidden in the App
33
The workflow is hidden in the App

Demo 5 : (App) Workflow hidden in the App
•Workflows in Apps : 2 main options:
Pattern 1.workflow is hidden in the App
Pattern 2.The workflow is visible in SharePoint (new since June 2014) = “Integrated workflow app” (!only O365)
36
Integrated workflow apps
• How to make an Integrated workflow app ?

Demo 6 : (App)Workflow visible in SharePoint
Conclusions
• Workflow Manager is nice, but no custom task forms/runtime Visio• Third party tools still in the SP 2010 “workflow
platform”• Don’t throw away the old workflow platform
• SharePoint Designer workflows can access Web Services & the SP api (REST)• Decouple your workflows !• Read (GET) easier than Modify (POST)
• Devs should always create VS workflows (Apps) in O365
• Task delegation is missing…
• Apps are the future…
• A real forms engine is missing ! (SP vNext)
