Agenda WSS v2 versus WSS v3 Architecture WSS v3 Storage Enhancements WSS v3 Customization Enhancements What’s 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 v2 versus WSS v3 WSS v2 IIS WSS v2 ISAPI Filter ASP.NET Handler ASP.NET WSS ISAPI Extension WSS Unmanaged Code ConfigContent Request.aspx.asmx Excluded PathsIncluded Paths WSS v3 IIS ASP.NET HTTP Modules Config Content Request ASP.NET HTTP Handlers WSS HTTP Modules WSS HTTP Handlers

What are the benefits? Inline now with ASP.NET 2.0 best practices for extensibility Virtual path provider allows for clean access to the SharePoint pages stored in the database New Web Part infrastructure Branding and customization based on ASP.NET 2.0 Master Pages and Provider Model Forms-based authentication Navigation controls

Architectural Enhancements

WSS v3 Storage General Platform Enhancements Top Requests Recycle Bin Security Trimming Item and Document Level Security Forced Check-Out Mobile Support

Top Requests for List and Document Library Enhancements

WSS v3 Storage List 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’

More Enhancements

WSS v3 Storage Extensibility 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

Extensibility Scenarios

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

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

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

Creating Custom Workflows SharePoint Designer for corporate Web designers Activities Re-use OOB/deployed activities Forms Autogenerated Forms -ASPX Deployment Workflow authored live against server Runtime compilation Development Model Wizard-based workflow designer Visual Studio Workflow Designer for professional developers Activities Re-use OOB/deployed activities Can author new activities Forms Designed Forms -InfoPath -ASPX Deployment Solutions package generated Box administrator installable Development Model Visual workflow designer

Creating a custom workflow with the SharePoint Designer

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)

Master Pages and WSS v3

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

‘Light-Up’ with Features

What’s New for Developers? ASP.NET 2.0 Web Parts Event Handlers

Web Parts in WSS v3 WSS V2 Runtime WSS Web Parts WSS V3 Runtime ASP.NET 2.0 Runtime ASP Web Parts Hybrid Web Parts WSS Web Parts

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(HtmlTextWriter writer) { writer.Write("Hello, world"); }

ASP.NET 2.0 Web Parts in WSS v3

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 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
