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.

LINQ

Language 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.
