Example:

class Animal {

    move(distanceInMeters: number) {
    console.log(`Animal moved`+distanceInMeters);

    }
}

class Dog extends Animal {

    bark()
         {
          console.log('Woof! Woof!');
         }

}

const dog = new Dog();

dog.bark();

dog.move(10);

dog.bark();

Public, private, and protected modifiers:

class Animal {

public name: string;

public constructor(theName: string)
{
  this.name = theName;
}

public move(distanceInMeters: number)
{
  console.log(`${this.name} moved ${distanceInMeters}m.`);
}
}

Module:

Inherit One Class functions or variables into other class is called Inheritance.

(or) inheritance is the concept that when a class , any subclass that is defined can inherit the definitions

**** Single Page Applications ****

- loading one template to another template without refreshing the whole web page
called as Single Page Application.

- loading one template to another template in Single Page Application called as
Routing.

- We will implement the Routing by using predefined Array called as "Routes"

- "RouterModule" is the Predefined Module used to load the "Routes"

- "Router" is the Predefined Class used to define the Dynamic URL'S.

- "Routes" , "RouterModule" & "Router" available in "@angular/router" module.

- the communication between components to services,
services to services,
components to directives,
components to pipes
---
---
called as Dependency Injection.

4) Single Page Application

- loading one template to another template without refreshing the
whole web page called as Single Page Application.

- loading one template to another template in Single Page Application
called as Routing.

- when ever we hit the server we are getting the "Observable" Response.

- map() is the predefined function used to catch the positive Observable Response.

- catch() is the predefined function used to catch the Negative Observable Response.

- "Positive Observable Response" is the "Response" Type.

- map(),catch() and next() functions are available in "rxjs/Rx" package.

- Observable also available in "rxjs" package.

Ex_1:

Step 1:
create the Angular6 Application

> ng new serEx1

- automatically "serEx1" project will be created.

Step 2:
create the custom service by using following command.

> ng g s services/countries

g stands for generate.

s stands for service

**** Forms *****

- In angular, we can design the forms.

- In Angular, we can design the forms in 2 ways.

1) TDF (Template Driven Forms)

2) MDF (Model Driven Forms) (MDF) (Reactive Forms)

- Template Driven Forms Mainly Based on View.

- Model Driven Forms mainly based on "Model Data".

- Angular By default apply the following validations on Forms.

1) dirty ==> pristine (when ever change detected)

2) touched ==> untouched (when ever we touch the fields)

3) valid ==> invalid (when ever we ignore the required rule

***** Model Driven Forms *****

- Model Driven Forms also called as Reactive Forms.

- Model Driven Forms mainly on Model.

create the anonymous function with 3 arguments.

name of variable - @fun_one

@arg1 - string
@arg2 - string
@arg3 - string

call the anonymous function with 3 arguments.

Ex_3:
one arrow function return another arrow function.

inner arrow function return "Welcome...!" message

Ex_4:
create arrow function with 3 arguments.

while calling the arrow function ,
"pass the definitions of anonymous functions"
as arguments.

- We can Declare the Functions with the help of "function" keyword.

- We Have Two Types of Functions.

1) Named functions

2) Anonymous Functions

Named functions
---------------
- The Function with the name called as Named function.

Syntax: Function definition

function function_name([arguments with datatype]):return type{

//Business Logic
}

//function calling
function_name();

=> create the flowing function with 3 arguments
@fun_one

=> arguments are string type.

=> call the fun_one.

Ex_3:
=> create the two functions
@fun_one
@fun_two

=> "fun_one" return "fun_two" definition.

=> "fun_two" return "welcome" message.

=> call "fun_one"

Ex_4:
create the following functions.

@fun_one
@fun_two

pass "fun_two" definition to "fun_one" as argument.

"fun_one" displays the argument.

"fun_two" return "welcome...!".

"fun_two" return "fun_three" definition.

"fun_three" return "Hello...!" message.

"fun_four" return "fun_five" definition.

"fun_five" return "Hi....!" message.

pass "fun_two" & "fun_four" definitions to "fun_one" as arguments.

"fun_one" calling should display "Hello...!" & "Hi...!" message

**** TypeScript ****

- TypeScript is the programming language.

- TypeScript Introduced by microsoft.

- Superset of JavaScript called as TypeScript.

- TypeScript Follows OOPS.

- Converting the TypeScript to Equalent JavaScript Called as "Transpilation".

- Web Pages(HTML Files) won't understands th TypeScript.

- As a TypeScript Developer we must perform the "Transpilation" Explicitely.

- "tsc" is a compiler used to perform the transpiltaion.

- "tsc" stands for "typescript compiler".

Installation of TypeScript:
---------------------------
1) download and install NodeJS

website : https://nodejs.org/en/download/

file : node-v8.11.2-x64.msi

2) Download and install VisualStudioCode.

website : https://code.viGit-2.17.0-64-bitsualstudio.com/docs/?dv=win

file : VSCodeSetup-x64-1.23.1.exe

3) download and install Git.

website : https://git-scm.com/download/win

file : Git-2.17.0-64-bit.exe

4) install "tsc" by using following command.

> npm install -g tsc

- "npm" stands node packaging manager.

- "npm" is the integrated tool of NodeJS.

- "-g" stands for global installation.

variables in TypeScript:
------------------------
- Variables are used to store the data.

- By using Variables we can store all categories of Data.

Ex.
string
number
boolean
Array
Objects
--
--
--

- we can declare variables by using either "var" keyword
or "let" keyword.

- we can save all the TypeScript files with the ".ts" extension.

- Transipilation gives the equalent javascript file.

Syn: var variable_name:data_type = "value"

Ex: var data:string = "Welcome...!"

Transplantation of variables.ts file:

=> open the Integrated Terminal in Visual Studio Code

=> execute the following command in integrated terminal

> tsc variables.ts

create the webpage:
index.html

<!DOCTYPE html>
<html>
<script src="variables.js"></script>
</html>

Pipes:
Pipes are used to format the data according to application requirement.We have two types of Pipes:

Predefined Pipes
Custom Pipes

The pipes given by angular framework called as Predefined Pipes.
The pipes developed by us based on application requirement called as custom pipe.

Predefined Pipes:

1) title-case: This pipe used to create the titles in angular application.

2) uppercase: This pipe used to convert the lowercase characters to uppercase characters.

3) lowercase: This pipe used to convert the uppercase characters to lowercase characters.

4) date: his pipe used to format the date according to application requirement.

5) currency: This pipe used to append the currency symbols to the numerical values.

6) json: This pipe used to convert the json objects to json strings.

7) number: This pipe used to format the numbers according to application requirement.

8) percent: This pipe used to convert the fractions to percentages.

9) async: This pipe used to append the values to the template asynchronously.

Classes

- Encapsulation of variables and functions called as Class.

- We Can Create the Class by using "class" keyword.

- we can declare constructor by using "constructor" keyword.

- we can create the objects to the class by using "new" keyword.

Ex_1:Create the class by using following name
@class_one

declare the following private variables
@sub_one - Angular6
@sub_two - NodeJS
@sub_three - MongoDB

declare the following public functions
@getSubOne() -- return "sub_one"
@getSubTwo() -- return "sub_two"
@getSubThree() -- return "sub_three"

initialize the variables by using constructor.

Ans:
Open Visual Code and Create one project with name Classes and create one type script class with name "classes" as screen short.

-->classes.ts

class class_one{
    private sub_one:string;
    private sub_two:string;
    private sub_three:string;
    constructor(){
        this.sub_one = "Angular6";
        this.sub_two = "NodeJS";
        this.sub_three = "MongoDB";
    }
    public getSubOne():string{
        return this.sub_one;
    }
    public getSubTwo():string{
        return this.sub_two;
    }
    public getSubThree():string{
        return this.sub_three;
    }
}
var obj:class_one = new class_one();
document.write( obj.getSubOne()+"...."+
                obj.getSubTwo()+"...."+
                obj.getSubThree());

Create one html with name index.html

<!DOCTYPE html>
<html>
<script src="classes.js"></script>
</html>

To compile typescript file we will use tsc in terminal in VS Code.
> tsc classes.ts

After compiling it will be generated one classes.js file as below:

class class_one{
    private sub_one:string;
    private sub_two:string;
    private sub_three:string;
    constructor(){
        this.sub_one = "Angular6";
        this.sub_two = "NodeJS";
        this.sub_three = "MongoDB";
    }
    public getSubOne():string{
        return this.sub_one;
    }
    public getSubTwo():string{
        return this.sub_two;
    }
    public getSubThree():string{
        return this.sub_three;
    }
}
var obj:class_one = new class_one();
document.write( obj.getSubOne()+"...."+
                obj.getSubTwo()+"...."+
                obj.getSubThree());

ASP.Net MVC Sample Application

2012-07-14T09:35:00.002-07:00

How to create a simple ASP.NET MVC program?

In this Exercise we will create a sample program using MVC template. So we will create a simple controller, attach the controller to simple index.aspx page and view the display on the browser.

Step1:- Create project

Create a new project by selecting the MVC 2 empty web application template as shown in the below figure

After click ok button then we get structure with appropriate folders where we can add controllers, models and views.

Step 2:- Add controller

So let’s go and add a new controller as shown in the below figure.

Once you add the new controller you should see some kind of code snippet as shown in the below snippet.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MyFirstMvcProg.Controllers
{
    public class Default1Controller : Controller
    {
        //
        // GET: /Default1/
        public ActionResult Index()
        {
            return View();
        }
    }
}

Step 3:- Add View

Now that we have the controller we need to go and add the view. So click on the Index function which is present in the control and click on add view menu as shown in the below figure.

The add view pops up a modal box to enter view name which will be invoked when this controller is called as shown in the figure below. For now keep the view name same as the controller name and also uncheck the master page check box.Once you click on the ok button of the view, you should see a simple ASPX page with the below HTML code snippet. In the below HTML code snippet I have added “This is my first MVC application”.

Step 4:- Run the application

If you do a CNTRL + F5 You get error because we have not invoked the appropriate controller / action.
If you append the proper controller on the URL you should be able to see the proper view.

WCF REST Service

2012-06-12T06:53:00.000-07:00

WCF REST Service

REST stands for Representational State Transfer and is an architectural style. REST provides an easier way of data access comparing with the SOAP protocol. REST and SOAP relies on HTTP protocol.REST provides an alternative to SOAP and WSDL.
REST uses some common HTTP methods to insert/delete/update/retrieve information which is below:

GET - Requests a specific representation of a resource
PUT - Creates or updates a resource with the supplied representation
DELETE - Deletes the specified resource
POST - Submits data to be processed by the identified resource

What is JSON?

JSON represents JavaScript Object Notation and is an open standard lightweight data interchange format in human readable form. Shortly, it is a data representation format.
JSON provides a simple alternative to the Fatty XML format of data representation. For example a class with properties name and age can be represented as:
eg:
{"Firstname" : "sudhakar",
"Lastname" : "Boyina",
"Address" : "Hyderabad"}

wcf Interview Questions and Answers

2012-06-10T06:23:00.002-07:00


	What is WCF? Windows Communication Foundation (WCF) is an SDK for developing and deploying services on Windows. WCF provides a runtime environment for services, enabling you to expose CLR types as services, and to consume other services as CLR types. WCF is part of .NET 3.0 and requires .NET 2.0, so it can only run on systems that support it. Difference between WCF and Web services? 1.Web Services can be accessed only over HTTP 2.Web Services works in stateless environment WCF is flexible because its services can be hosted in different types of applications. The following lists several common scenarios for hosting WCF services: 1. IIS 2. WAS 3. Self-hosting 4. Managed Windows Service
	What are the various ways of hosting a WCF service? Self hosting the service in his own application domain. This we have already covered in the first section. The service comes in to existence when you create the object of ServiceHost class and the service closes when you call the Close of the ServiceHost class. Host in application domain or process provided by IIS Server. Host in Application domain and process provided by WAS (Windows Activation Service) Server.
	What are three major points in WCF? We Should remember ABC. Address - Specifies the location of the service which will be like http://Myserver/MyService.Clients will use this location to communicate with our service. Binding - Specifies how the two paries will communicate in term of transport and encoding and protocols. Contract - Specifies the interface between client and the server.It's a simple interface with some attribute.
	What was the code name for WCF? The code name of WCF was Indigo . WCF is a unification of .NET framework communication technologies which unites the following technologies:- NET remoting MSMQ Web services COM+
	What are the main components of WCF? The main components of WCF are 1. Service class 2. Hosting environment 3. End point
	What are different elements of WCF Srevices Client configuration file? WCF Services client configuration file contains endpoint, address, binding and contract. A sample client config file looks like
	What is Proxy and how to generate proxy for WCF Services? WCF Services client configuration file contains endpoint, address, binding and contract. A sample client config file looks like The proxy is a CLR class that exposes a single CLR interface representing the service contract. The proxy provides the same operations as service's contract, but also has additional methods for managing the proxy life cycle and the connection to the service. The proxy completely encapsulates every aspect of the service: its location, its implementation technology and runtime platform, and the communication transport. The proxy can be generated using Visual Studio by right clicking Reference and clicking on Add Service Reference. This brings up the Add Service Reference dialog box, where you need to supply the base address of the service (or a base address and a MEX URI) and the namespace to contain the proxy. Proxy can also be generated by using SvcUtil.exe command-line utility. We need to provide SvcUtil with the HTTP-GET address or the metadata exchange endpoint address and, optionally, with a proxy filename. The default proxy filename is output.cs but you can also use the /out switch to indicate a different name. SvcUtil http://localhost/MyService/MyService.svc /out:Proxy.cs When we are hosting in IIS and selecting a port other than port 80 (such as port 88), we must provide that port number as part of the base address: SvcUtil http://localhost:88/MyService/MyService.svc /out:Proxy.cs
	What are contracts in WCF? In WCF, all services expose contracts. The contract is a platform-neutral and standard way of describing what the service does. WCF defines four types of contracts. Service contracts Describe which operations the client can perform on the service. There are two types of Service Contracts. ServiceContract - This attribute is used to define the Interface. OperationContract - This attribute is used to define the method inside Interface. [ServiceContract] interface IMyContract { [OperationContract] string MyMethod( ); } class MyService : IMyContract { public string MyMethod( ) { return "Hello World"; } } Data contracts Define which data types are passed to and from the service. WCF defines implicit contracts for built-in types such as int and string, but we can easily define explicit opt-in data contracts for custom types. There are two types of Data Contracts. DataContract - attribute used to define the class DataMember - attribute used to define the properties. [DataContract] class Contact { [DataMember] public string FirstName; [DataMember] public string LastName; } If DataMember attributes are not specified for a properties in the class, that property can't be passed to-from web service. Fault contracts Define which errors are raised by the service, and how the service handles and propagates errors to its clients. Message contracts Allow the service to interact directly with messages. Message contracts can be typed or untyped, and are useful in interoperability cases and when there is an existing message format we have to comply with.
	What is the address formats of the WCF transport schemas? Address format of WCF transport schema always follow [transport]://[machine or domain][:optional port] format. for example: HTTP Address Format http://localhost:8888 the way to read the above url is "Using HTTP, go to the machine called localhost, where on port 8888 someone is waiting" When the port number is not specified, the default port is 80. TCP Address Format net.tcp://localhost:8888/MyService When a port number is not specified, the default port is 808: net.tcp://localhost/MyService NOTE: Two HTTP and TCP addresses from the same host can share a port, even on the same machine. IPC Address Format net.pipe://localhost/MyPipe We can only open a named pipe once per machine, and therefore it is not possible for two named pipe addresses to share a pipe name on the same machine. MSMQ Address Format net.msmq://localhost/private/MyService net.msmq://localhost/MyService
	What is endpoint in WCF? Every service must have Address that defines where the service resides, Contract that defines what the service does and a Binding that defines how to communicate with the service. In WCF the relationship between Address, Contract and Binding is called Endpoint. The Endpoint is the fusion of Address, Contract and Binding.
	What is binding and how many types of bindings are there in WCF? A binding defines how an endpoint communicates to the world. A binding defines the transport (such as HTTP or TCP) and the encoding being used (such as text or binary). A binding can contain binding elements that specify details like the security mechanisms used to secure messages, or the message pattern used by an endpoint. WCF supports nine types of bindings. Basic binding Offered by the BasicHttpBinding class, this is designed to expose a WCF service as a legacy ASMX web service, so that old clients can work with new services. When used by the client, this binding enables new WCF clients to work with old ASMX services. TCP binding Offered by the NetTcpBinding class, this uses TCP for cross-machine communication on the intranet. It supports a variety of features, including reliability, transactions, and security, and is optimized for WCF-to-WCF communication. As a result, it requires both the client and the service to use WCF. Peer network binding Offered by the NetPeerTcpBinding class, this uses peer networking as a transport. The peer network-enabled client and services all subscribe to the same grid and broadcast messages to it. IPC binding Offered by the NetNamedPipeBinding class, this uses named pipes as a transport for same-machine communication. It is the most secure binding since it cannot accept calls from outside the machine and it supports a variety of features similar to the TCP binding. Web Service (WS) binding Offered by the WSHttpBinding class, this uses HTTP or HTTPS for transport, and is designed to offer a variety of features such as reliability, transactions, and security over the Internet. Federated WS binding Offered by the WSFederationHttpBinding class, this is a specialization of the WS binding, offering support for federated security. Duplex WS binding Offered by the WSDualHttpBinding class, this is similar to the WS binding except it also supports bidirectional communication from the service to the client. MSMQ binding Offered by the NetMsmqBinding class, this uses MSMQ for transport and is designed to offer support for disconnected queued calls. MSMQ integration binding Offered by the MsmqIntegrationBinding class, this converts WCF messages to and from MSMQ messages, and is designed to interoperate with legacy MSMQ clients.
	Where we can host WCF services? Every WCF services must be hosted somewhere. There are three ways of hosting WCF services. They are 1. IISM 2. Self Hosting 3. WAS (Windows Activation Service)
	What is address in WCF and how many types of transport schemas are there in WCF? Address is a way of letting client know that where a service is located. In WCF, every service is associated with a unique address. This contains the location of the service and transport schemas. WCF supports following transport schemas HTTP TCP Peer network IPC (Inter-Process Communication over named pipes) MSMQ The sample address for above transport schema may look like http://localhost:81 http://localhost:81/MyService net.tcp://localhost:82/MyService net.pipe://localhost/MyPipeService net.msmq://localhost/private/MyMsMqService net.msmq://localhost/MyMsMqService
	What is service and client in perspective of data communication? A service is a unit of functionality exposed to the world. The client of a service is merely the party consuming the service

Difference between WCF and Web service

2012-06-10T06:11:00.004-07:00

Web Service in ASP.NET

A Web Service is programmable application logic accessible via standard Web protocols. One of these Web protocols is the Simple Object Access Protocol (SOAP). SOAP is a W3C submitted note (as of May 2000) that uses standards based technologies (XML for data description and HTTP for transport) to encode and transmit application data.
Consumers of a Web Service do not need to know anything about the platform, object model, or programming language used to implement the service; they only need to understand how to send and receive SOAP messages (HTTP and XML).

WCF Service

Windows Communication Foundation (WCF) is a framework for building service-oriented applications. Using WCF, you can send data as asynchronous messages from one service endpoint to another. A service endpoint can be part of a continuously available service hosted by IIS, or it can be a service hosted in an application. An endpoint can be a client of a service that requests data from a service endpoint. The messages can be as simple as a single character or word sent as XML, or as complex as a stream of binary data.
In what scenarios must WCF be used

A secure service to process business transactions.
A service that supplies current data to others, such as a traffic report or other monitoring service.
A chat service that allows two people to communicate or exchange data in real time.
A dashboard application that polls one or more services for data and presents it in a logical presentation.
Exposing a workflow implemented using Windows Workflow Foundation as a WCF service.
A Silverlight application to poll a service for the latest data feeds.

Features of WCF

Difference between Web Service in ASP.NET & WCF Service

Web service is a part of WCF. WCF offers much more flexibility and portability to develop a service when comparing to web service. Still we are having more advantages over Web service, following table provides detailed difference between them.

Features	Web Service	WCF
Hosting	It can be hosted in IIS	It can be hosted in IIS, windows activation service, Self-hosting, Windows service
Programming	[WebService] attribute has to be added to the class	[ServiceContraact] attribute has to be added to the class
Model	[WebMethod] attribute represents the method exposed to client	[OperationContract] attribute represents the method exposed to client
Operation	One-way, Request- Response are the different operations supported in web service	One-Way, Request-Response, Duplex are different type of operations supported in WCF
XML	System.Xml.serialization name space is used for serialization	System.Runtime.Serialization namespace is used for serialization
Encoding	XML 1.0, MTOM(Message Transmission Optimization Mechanism), DIME, Custom	XML 1.0, MTOM, Binary, Custom
Transports	Can be accessed through HTTP, TCP, Custom	Can be accessed through HTTP, TCP, Named pipes, MSMQ,P2P, Custom

Windows Communication Foundation 3.5 Unleashed Book

Publisher: S.a.m.s 2008 | 768 Pages | ISBN: 0672330245 | PDF | 14 MB
Windows Communication Foundation (WCF) is Microsoft’s dynamic technology for allowing autonomous software to communicate. Superseding earlier technologies such as COM/DCOM, .NET Remoting, ASP.NET Web Services, and the Web Services Enhancements for .NET, WCF provides a single solution that is designed to always be the best way to exchange data among software entities. It also provides the infrastructure for developing the next generation of Web Services, with support for the WS-* family of specifications, and a new serialization system for enhanced performance. In the 3.5 release, WCF has been expanded to include support for REST, JSON, and Syndication (RSS and Atom) services, further broadening the possibilities for what can be done. For information technology professionals, WCF supplies an impressive array of administration tools that enterprises and software vendors can use to reduce the cost of ownership of their solutions without writing a single line of code. Most important, WCF delivers on the promise of model-driven software development with the new software factory approach, by which one can iteratively design solutions in a modeling language and generate
executables from lower-level class libraries.

WINDOWS COMMUNICATION FOUNDATION

Overview

Windows Communication Foundation takes many existing communication technologies, such as Web Services, Windows Remoting, Microsoft Message Queuing, and abstracts them into a single technology. In most cases, this simplifies the way you communicate with other applications. It also allows you to communicate with other applications without being coupled to a specific technology. Therefore, you could use Web Services over SOAP to begin with, and later move to remote procedure calls (RPC) without changing your code, just the configuration of WCF.

The Basics

There are a few basic tasks when creating a WCF service. The basic tasks that must be performed are, in order:

Define the service contract. A service contract specifies the signature of a service, the data it exchanges, and other contractually required data.
Implement the contract. To implement a service contract, create the class that implements the contract and specify some custom behaviors that the runtime should have.
Configure the service by specifying endpoint information and other behavior information.
Host the service in an application.
Build a client application.

For more information, see http://msdn2.microsoft.com/en-us/library/ms732098.aspx

Example

To display a step-by-step enactment of the above steps, let’s define a web service that reports the current date/time:

1.1 Define a Service Contract

First, let’s create a project to house our service contract. Let’s call it WCFDateTime.Service.

1.2 Define a Service Contract

Then, let’s define an interface that represents the service we’re going to provide. In this case, let’s call it IDateTimeService.

public interface IDateTimeService

{

}

1.3 Define a Service Contract

We need to add a method to our service that will return the current date/time:

public interface IDateTimeService

{

DateTime GetCurrentDateTime();

}

1.4 Define a Service Contract

Now, we need to decorate our code with attributes so that WCF will recognize our interface and its methods. Namely, we will add the following attributes:

· ServiceContractAttribute

o Identifies an interface as a WCF service contract

· OperationContractAttribute

o Identifies methods of an interface as WCF service operations, that is, methods that can be called through WCF

using System.ServiceModel;

[ServiceContract]

public interface IDateTimeService

{

[OperationContract]

DateTime GetCurrentDateTime();

}

In order to use the above attributes, you’ll need to add a reference to the System.ServiceModel assembly. The service contract is now ready to be used.

2.1 Implement the Contract

Now that we’ve defined our service contract, we can move on to implementing it. First, let’s create another project to house our server application. Let’s call it WCFDateTime.Server, and make it a Console Application project.

2.2 Implement the Contract

Now, let’s implement the IDateTimeService. The implementation is going to run on our server, to provide the date/time to whoever is going to consume our service.

In the WCFDateTime.Server project, let’s create a class called DateTimeService and have it implement IDateTimeService:

using WCFDateTime.Service;

public class DateTimeService : IDateTimeService

{

}

Remember to add a reference to the WCFDateTime.Service project so you can use IDateTimeService.

2.3 Implement the Contract

The above code will obviously not compile, because we did not implement the GetCurrentDateTime method:

public class DateTimeService : IDateTimeService

{

public DateTime GetCurrentDateTime()

{

return DateTime.Now;

}

That’s it! The DateTimeService is now ready to be used.

3.1 Configure the Service

Now we need to configure our service so it can be consumed by client applications. The simplest way to accomplish this is by adding an application configuration file (app.config or web.config) to the WCFDateTime.Server project:

<?xml version="1.0" encoding="utf-8" ?>

<system.serviceModel>

<endpoint

address="http://localhost:8081/DateTimeService"

binding="wsHttpBinding"

contract="WCFDateTime.Service.IDateTimeService" />

</service>

</services>

</system.serviceModel>

</configuration>

When defining an endpoint for WCF, remember your A-B-Cs:

1. Address (where)

2. Binding (how)

3. Contract (what)

The address specifies the address where you want the service to be located.

The binding specifies the transport you want to use in order to provide the service.

The contract specifies what service will be provided

4.1 Host the Service in an Application

Now that WCF has been configured, the simplest way to host this service is to create a Console Application and use the ServiceHost class. First, add a reference to the System.ServiceModel assembly. Then, In the program.cs file of WCFDateTime.Server, do the following:

using System.ServiceModel;

namespace WCFDateTime.Server

{

class Program

{

static public void Main(string[] args)

{

// Get a host for our service

ServiceHost serviceHost = new ServiceHost(

typeof(DateTimeService)

);

// Open the service host to start listening for incoming requests

serviceHost.Open();

// The service can now be accessed

Console.WriteLine("The service is ready.");

Console.WriteLine("Press <ENTER> to terminate service.");

Console.ReadLine();

// Close the service host

serviceHost.Close();

}

By simply running this application, we expose our service so that client applications can use it.

5.1 Build a Client Application

To build a client application, we must create a new project for it. Let’s call it WCFDateTime.Client, and make it a Console Application as well.

5.2 Build a Client Application

Now, we need to add an Application Configuration file, and give it some settings that will allow us to connect to the service we just created:

<?xml version="1.0" encoding="utf-8"?>

<system.serviceModel>

<endpoint

address="http://localhost:8081/DateTimeService"

binding="wsHttpBinding"

contract="WCFDateTime.Service.IDateTimeService"

name="MyDateTimeService">

</endpoint>

</client>

</system.serviceModel>

</configuration>

Now that our we’ve configured our WCF client, we can connect to it. There are two ways to connect to the WCF service we previously created:

1. Client proxy generation

2. Channel factories

Most Microsoft articles will point you in the direction of using client proxies; however, for our purposes, channel factories are quicker to implement and more robust in a Model/View/Presenter architecture.

5.3 Build a Client Application

Now, add a reference to the System.ServiceModel and WCFDateTime.Service assemblies, and then add the following to the program.cs file:

using System.ServiceModel;

using WCFDateTime.Service;

class Program

{

public static void Main(string[] args)

{

// Get a channel factory for our service,

// using the configuration for "MyDateTimeService"

// in the application configuration file.

ChannelFactory<IDateTimeService> channelFactory =

new ChannelFactory<IDateTimeService>("MyDateTimeService");

// Get an instance of our service

IDateTimeService service = channelFactory.CreateChannel();

// Get the server’s date/time

DateTime dt = service.GetCurrentDateTime();

// Write the current server date/time

Console.WriteLine("The current server time is " + dt);

// Close the connection to our service

channelFactory.Close();

}

5.4 Build a Client Application

Your client application is now ready to run! Simply start the WCFDateTime.Server application, and once it’s running, run the WCFDateTime.Client application to see it work!
