Windows Workflow Foundation (WF)
  Single workflow technology for Windows
     Extensible framework & toolset
     Base platform for Microsoft, ISV and customer solutions
  A framework for building workflow into applications
     A framework to build on - not an application or server
     Exposed to developers via .NET 3.0

                        Windows Workflow Foundation (WF)

                                 .NET 3.0/3.5 Framework
                      Windows Operating Systems (Client and Server)
What are workflows?
 Encapsulated logic for coordinating business processes
    provides abstractions to model real world processes
    valuable for modeling long running and stateful behavior
    Workflows in WF are decomposed into activities



   Sequential workflows                      State machine workflow




    modeled as flowchart                    modeled as state diagram
.. What is MS Workflow ?

  Workflow is a natural way to organize and run a set of work units, or
  activities, to form an executable file representation of a work process
  Microsoft Windows platform component that provides a programming
  framework and tools for development and execution of workflow-
  based applications

What are activities?
  Activities are reusable components (like form controls)
     Model based on activity producers and consumers
     Producer encapsulates logic into reusable black box
     Producer exposes behavior through properties and events
     Consumer drops activity on workflow designer in Visual Studio

WSS Workflow Fundamentals

  WSS supports workflows on items and documents
     WF associated with list, document library or content type
     WF can be started and completed by user actions
     WF can be configured to start without user action

  WSS adds a dimension of human accountability
     All WSS workflows are associated with a task list

  WSS adds a dimension of tracking and reporting
     All WSS workflows are associated with a workflow history list

Using The Workflow
Developing Workflow
Tools Comparison
   Using Visual Studio.net Designer
      It’s not for a specific Sharepoint Site
      Developing custom code to your activities
      Design Forms to communicate with users
      Done by Professional Developer
      Can author both sequential and state workflows
   Using Sharepoint Designer
      It’s for a specific Sharepoint Site
      Code-free, declarative rules-based workflows .
      you are in effect assembling pre-existing activities into
      workflows
      Likely Done by Web designer or Knowledge worker.
      Can Author sequential workflow only.

What Is SharePoint Designer?
 New product targeted at enterprise solution
 creators and designers using SharePoint
 technologies
 Great web design tool
   High quality design surface and integrated code view
   Deep web standards support (XHTML, CSS, XSLT,
   XML)
   Excellent ASP.NET support (control hosting, prop
   editing, data binding, intellisense)
 Part of MS family of web tools:
   Microsoft Office SharePoint Designer
   Expression Web Designer
   Visual Studio Web Developer
The Workflow Designer
Creating application logic without code
Workflow Designer Overview

  RAD workflow development tool
  Deep SharePoint integration
  Low barrier to entry
  Enables new scenarios:
    Custom SharePoint List logic
    Reporting & tracking apps (event-based)
Rule-Based “No Code” Workflows
 Built on Windows Workflow Foundation hosting in SharePoint
 Workflows are composed of pre-existing building blocks and
 conditional logic
    Based on Events, Conditions, and Actions
    Described by XOML files in web site
    Triggered by initiation form or list events
    Supports rich data binding to list items
 Extensible via custom actions, conditions
Sample Workflow Actions

    Assign Custom Task
    Send Email
    Create/Update/Delete List item
    Collect Feedback
    Wait for Timer
    Wait for Data Change
Creating a custom workflow in Sharepoint Designer
Development Steps


1.   Model workflow in Visual Studio
2.   Create and bind InfoPath forms
3.   Deploy to SharePoint server
4.   Debug the running workflow
            Workflow Deployment

Compile your workflow template as a strong-named
assembly.
Create the feature definition file that provides Windows
SharePoint Services with the information necessary to
deploy your workflow at the specified scope.
Create the workflow definition file that provides Windows
SharePoint Services with the information necessary to
instantiate and run the workflow.
Set the deploy property so that building the solution
deploys the workflow files to the correct location, copies
the workflow assembly to the global assembly cache
(GAC), and activates the workflow feature in Windows
SharePoint Services.
  Model Workflow In Visual Studio
   Prerequisites:
      Visual Studio 2005 extensions for WF – (RC5)
      SharePoint 2007 SDK – Visual Studio templates for SharePoint workflow
   Create project of type “SharePoint Sequential Workflow Library”

Advanced Workflow Features
Collaboration and Communications
  Information workers need tools to enable them to work collectively
  irrespective of any geographical barriers.


Unified Communications

                          for SharePoint Server 2007
Business Processes
         Organisations need tools to define a collection of related structural
         activities that produce something of value
         Information workers need tools to enable them to easily undertake these
         activities providing appropriate inputs and handling the outputs.
