Agenda

• WSS v2 versus WSS v3 Architecture
• WSS v3 Storage Enhancements
• WSS v3 Customization Enhancements
• Whats New for Developers in WSS v3

WSS v3 Architecture

• Software Requirements
• Windows Server 2003
• .NET Framework 2.0
• IIS 6.0 (worker process isolation mode)
• Windows Workflow Foundation (WF)
• SQL Server 2000 (SP3) or SQL Server 2005
• Better ASP.NET 2.0 citizen than WSS v2
• No more ISAPI filter
• WSS extensions now based on HttpModules and
  HttpHandlers

WSS v3 Storage General Platform Enhancements

• Top Requests
• Recycle Bin
• Security Trimming
• Item and Document Level Security
• Forced Check-Out
• Mobile Support

8
Top Requests for List and Document Library
Enhancements

WSS v3 StorageList and Document Enhancements

• New Field Types
• Multi-value lookups, append-only, person
• Column Indexing and Cross-Site Queries
• Versioning
• Major and minor versions
• Version pruning
• Versioning in lists
• RSS Feed Support
• Off-line support in Outlook 12

10
More Enhancements
11
WSS v3 StorageExtensibility Enhancements

• Shared Columns
• Content Types
• List and libraries can now store more than one
  type of item or document
• Every type can have its own metadata, workflow,
  event handlers and policies
• Field Types are extensible now

12
Extensibility Scenarios
13
Windows WorkFlow Foundation

• Single workflow technology for Windows
• Extensible framework toolset
• Base for Microsoft products and customer
  solutions
• Transform workflow from niche to mainstream
  paradigm
• Exposed to developers via WinFX

14
Workflow Basics

• Custom Workflow consists out of one or more
  activities
• Activity Libraries
• WF Base Activity Library
• O12 Activity Library
• Custom Libraries
• Activity is a class
• Events/Properties
• Methods called by WF Runtime engine
• WF created using Visual Studio.NET
• Deployed as .NET assembly

15
WSS v3 and WF

• WSS supports workflows on items and documents
• Workflows associated with list, document library
  or content type
• Workflow started and completed by user actions
• Workflows are managed using WSS task lists
• Workflow-related task lists use standard WSS task
  list schema
• Workflow activities create and update task items
  as required
• Workflows are tracked through history tables
• Allows users to see workflow progress

16
Creating Custom Workflows
SharePoint Designer for corporate Web designers
Visual Studio Workflow Designer for professional
developers
Development Model Visual workflow designer
Development Model Wizard-based workflow designer
Activities Re-use OOB/deployed activities

• Workflow authored live against server
• Runtime compilation

WSS v3 Master Pages

• Master Pages are a primary feature in ASP.NET 2.0
• Provides effective template solution for pages
  within site
• Content page reuses chrome from master page
• Content page fill in placeholders defined in
  master page
• WSS v3 embraces ASP.NET master pages
• WSS sites such as Team Site built using a
  standard master page
• Quick and easy to change look and feel of entire
  site
• Editing master page can be done with SharePoint
  Site Designer
• How do master pages work in WSS?
• Each site page in WSS site points to a master
  page
• Each WSS site has a Master Page Gallery (MPG)

WSS v3 Features Framework

• Innovation to enhance modular provisioning
• Group logical elements into scenario-driven
  features
• Features can be add to and reused across site
  definitions
• New features can be activated in existing site to
  add functionality
• Features scoped at web, site, web application,
  farm

Whats New for Developers?

• ASP.NET 2.0 Web Parts
• Event Handlers

ASP.NET 2.0 Web Parts in WSS v3

• Web Parts derive from WebPart base class
• All Web Part inherit common functionally

using System using System.Web.UI using
System.Web.UI.WebControls.WebParts namespace
LitwareWebParts public class
HelloWorldWebPart WebPart protected
override void OnPreRender(EventArgs e)
this.Title "Litware Project Revenue"
protected override void RenderContents(HtmlTextWr
iter writer) writer.Write("Hello,
world")

WSS v3 Event Handlers

• Events architecture significantly improved
• Events supported for lists, document libraries
  and content types
• Events supported for changes to list schema as
  well as items
• Events supported at site collection and site
  level
• Events supported for incoming email messages
• Support for synchronous events and asynchronous
  events
• Synchronous events occur before the fact and are
  cancel-able
• How do you get events to work
• Create custom class inheriting a WSS receiver
  class e.g. SPItemEventReceiver or
  SPWebEventReciever
• Compile class into assembly DLL and install in
  GAC
• Add event configuration by installing and
  activating a feature
