WCF 4.0 comes with improved support for REST-based features

Implementing the TestService WCF Service

The WCF Service class called TestService implements the WCF Service Contract implemented earlier -- it defines the two methods declared in the WCF Service Contract. Here's what the class looks like:

<%@ ServiceHost Language="C#" Debug="true" Service="RESTService.TestService" CodeBehind="TestService.svc.cs" %>

using System;

using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;

namespace RESTService
{

[ServiceContract]
public interface ITestService
{
[OperationContract]
[WebGet]
Employee GetEmployee(Int32 employeeID);
[WebInvoke]
Employee PostEmployee(Int32 employeeID);
}

[DataContract(Namespace = "")]
public class Employee
{
[DataMember]
public Int32 EmployeeID { get; set; }
[DataMember]
public string FirstName { get; set; }
[DataMember]
public string LastName { get; set; }
[DataMember]
public String Address { get; set; }
}

public class TestService : ITestService
{
public Employee GetEmployee(Int32 employeeID)
{
return new Employee { EmployeeID = employeeID, FirstName = "Joydip", LastName = "Kanjilal" };
}

public Employee PostEmployee(Int32 employeeID)
{
return new Employee { EmployeeID = employeeID, FirstName = "Joydip", LastName = "Kanjilal" };
}
}
}
