1. .NET 3.0, 3.5, 4.0WCF, WPF, WF, CardSpace, LINQ,Task Parallel

3. Windows Communication Foundation(WCF)

4. WCF: Windows Communication Foundation • For distributed applications. • Using service oriented architecture (SOA). • Clients can consume multiple services; Services can be consumed by multiple clients. (M:M) • Services have WSDL interface. • WCF examples: WSS (Web Services Security, extension to SOAP to apply security to web services), WS-Discovery (Web Services Dynamic Discovery, a multicast discovery protocol to locate services),

5. WCF: Windows Communication Foundation • Endpoints: client connects to a WCF service at an Endpoint, each service exposes its contract via endpoints. • End point ABC: address, binding, contract • WCF endpoints use SOAP envelope to communicate with clients (for platform independence). • Behaviors allow the developer to customize how the messages are handled.

6. Windows Presentation Foundation(WPF)

7. WPF: Windows Presentation Foundation • Graphical subsystem. • Based on DirectX • 2D and 3D graphics, vector graphics and animation • Remote or standalone • Safe remote view with IE. • Uses XAML to define UI elements. • XAML: eXtensible Application Markup Language

8. Windows Workflow Foundation(WF)

9. WF: Windows Workflow Foundation • Workflow: a series of distinct programming steps. • An activity at each step. • Workflow Designer in Visual Studio. • Workflow engine: scheduling, managing, tracking workflows. • To create applications that execute an ordered business process (UA curriculum proposal approval system).

10. Windows CardSpace

11. Windows CardSpace • Identification metasystem. • Resistance to phishing attacks • Follow the “7 laws of identity” (User Control and Consent, Minimal Disclosure for a Constrained Use, Justifiable Parties, Directed Identity, Pluralism of Operators and Technologies, Human Integration, Consistent Experience Across Contexts) • To be replaced by U-Prove.

12. LINQLanguage Integrated Query

13. Embedded SQL in C# as strings StringBuilder builder = new StringBuilder(); builder.Append ("select count(*) from users " + "whereusername = \'"); builder.Append (username); builder.Append ("\' and pwd = \'"); builder.Append (password); builder.Append ("\';"); MySqlCommand command = new MySqlCommand (builder.ToString (), connection); Int64 count = (Int64) command.ExecuteScalar ();

14. LINQ: Language Integrated Query var results = from c in SomeCollection wherec.SomeProperty < 10 select new {c.SomeProperty}; foreach (var result in results) Console.WriteLine(result);

15. Task Parallel

16. Parallel Extensions • Managed concurrency library • TPL: Task Parallel Library • PLINQ: Parallel LINQ • Multithreading based. • Take advantages of muti-core (Intel) and many core (Nvidia GPU)

17. That’s all. Folks.
