Task Parallel

Windows Communication Foundation

(WCF)

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),

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.

Windows Presentation Foundation (WPF)

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

Windows Workflow Foundation (WF)

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).

Windows CardSpace

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.

LINQLanguage Integrated Query

Embedded SQL in C# as strings

StringBuilder builder = new StringBuilder (); builder.Append ("select count(*) from users " + "where username = \'"); builder.Append (username); builder.Append ("\' and pwd = \'"); builder.Append (password); builder.Append ("\';"); MySqlCommand command = new MySqlCommand (builder.ToString (), connection);

Int64 count = (Int64) command.ExecuteScalar ();

LINQ: Language Integrated Query

var results = from c in SomeCollection where c.SomeProperty < 10 select new {c.SomeProperty};

foreach (var result in results) Console.WriteLine(result);

Task Parallel

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)

That’s all. Folks.
