The document discusses the .NET Framework 3.5, including what's new in 3.5 compared to previous versions. Key additions in 3.5 include Language Integrated Query (LINQ) for querying data from various sources using a SQL-like syntax, improved support for ASP.NET AJAX, new protocols like REST in Windows Communication Foundation (WCF), and full tooling support in Visual Studio 2008. The document also provides overviews of Windows Presentation Foundation (WPF), Windows Workflow Foundation (WF), and WCF.

2. Agenda Why do you need .NET Framework 3.5? What’s new in .NET Framework 3.5? When can you get .NET Framework 3.5? What is Microsoft .NET Framework 3.5? What is the Microsoft .NET Framework? Questions and answers What’s new in .NET Framework 3.0?

3. Microsoft Application Platform

4. What is Microsoft .NET Framework 3.5? 2.0 = ASP.NET, CLR, Web Services, WinForms 3.0 = Cardspace, WCF, WF, WPF 3.5 = AJAX, LINQ, REST, RSS .NET Framework 3.5 .NET Framework 3.0 SP1 Microsoft Visual Studio 2008 .NET Framework 2.0 SP1

5. Why do you need .NET Framework 3.5? Create applications that run anywhere: mobile devices, browsers, desktops, and servers Enables better collaboration between developers and designers to create rich user experiences Productivity improvements like LINQ to provide a single platform for quickly building apps that run anywhere Simplifies building applications with messaging systems and/or workflows Connected Compelling Ubiquitous & Productive

6. What was new in .NET Framework 3.0? build user interfaces for applications and media-rich experiences build and run connected systems - focus on Web services build workflow-enabled applications build secure online user authentication .NET FRAMEWORK Windows Presentation Foundation (WPF) Windows Workflow Foundation (WF) Windows Communication Foundation (WCF) Windows Cardspace

7. Demo – Basic WCF What/Why WCF? Services (service or data contacts) + hosts (self, console, IIS, WAS…) + clients USE Endpoints (address, binding, contract) Web services, remoting + more Flexible, re-usable SOA

8. What’s new in .NET Framework 3.5? Language Integrated Query (LINQ) ASP.NET AJAX support for Web 2.0-style applications New Web protocols in WCF – REST + Syndication (RSS/ATOM) Exposing WF workflows as WCF services Full tooling support in VS2008 for WF, WCF, and WPF .NET FRAMEWORK WPF WF WCF CS

9. What’s new in .NET Framework 3.5? LINQ Language extensions to C#/VB.NET ® that add native data querying capabilities, using a syntax like SQL to nearly ANY data source Lets you write code in any LINQ-enabled language to filter, enumerate, and create projections of several types of SQL data, collections, XML, and DataSets by using the same syntax Enables better programming productivity and simpler, easier-to-maintain code .NET FRAMEWORK WPF WF WCF CS

10. Programming with objects Unified Query Constructs across all data XML, SQL Server or Object collections IntelliSense, syntax checking, debugging within VS2008 (C# and VB)

11. What’s new in .NET Framework 3.5 for WCF? ASP.NET AJAX support for Web 2.0-style applications WCF calls via AJAX, automatic proxy generation ala the AJAX toolkit for .asmx in .NET 3.0 AJAX services with JavaScript Object Notation (JSON) encoding .NET FRAMEWORK WPF WF WCF CS

12. What’s new in .NET Framework 3.5 for WCF? Representational State Transfer (REST) services with JSON, POX or binary encoding New binding WebHttpBinding alternative to SOAP – no envelope, simpler, more flexible, no WSDL Uses HTTP GET, POST, etc.. via [WebGet], [WebInvoke] URI templates Unified feeds with RSS or ATOM syndication format encoding New types – Syndication Feed/Item .NET FRAMEWORK WPF WF WCF CS

13. What’s new in .NET Framework 3.5 for WCF? Several other new WS-* standards implementations WS – Security/Trust/Secure Conversation == Security WS – Reliable Messaging == Reliability WS- Policy == Metadata (ala WSDL) WS – Coordination / Atomic Transactions == Transactions WS – Addressing == Routing .NET FRAMEWORK WPF WF WCF CS

14. What’s new in .NET Framework 3.5? New classes in base class library to address customer requests Example: Support for building high-performance peer-to-peer applications by using the Peer Name Resolution Protocol Integrated with Event Tracking for Windows New add-in hosting model for extensibility .NET FRAMEWORK WPF WF WCF CS

15. What’s new in .NET Framework 3.5? Full tooling support in Visual Studio 2008 for WF, WCF, and WPF Workflow-enabled services for WF Visual designers for WPF Project templates for WCF services .NET FRAMEWORK WPF WF WCF CS

16. Productivity Workflow and communications Workflow and Communication Framework Workflows for business processes Hook code into workflow events Unified programming model for a variety of communications Supporting a heterogeneous services architecture is complex Challenge Solution

17. Why WF? Visual model for business rules simple/complex, code or declarative rules Machine or Human Sequential or state workflows Plumbing written for you Maintain state via hydration, Monitor Re-use / Maintain / Update / Connect Activity-based, updatable, use w/WCF

18. Demo CHC WCF improvements WCF/WF Integration LINQ

19. Demo @Sales WCF improvements REST and SOAP AJAX integration RSS/ATOM types
