How to create WCF RESTful Service.

In my earlier blog, I have explained about REST and SOAP.
In this blog, I will continue WCF tutorial sections. See a list of topic in WCF tutorial here.
REST is the short form of Representational State Transfer. REST says each resource should be accessed by URI.

How to create a RESTful WCF service.

First, create a WCF service application in Visual Studio and delete existing service and interface file.
Right-click on the project and add a new WCF service and name it ProductService.

Service Contract

namespace WCFRESTServiceDemo

{

// NOTE: You can use the “Rename” command on the “Refactor” menu to change the interface name “IProductService” in both code and config file together.

[ServiceContract]

public interface IProductService

{

[OperationContract]

[WebGet(UriTemplate = “/GetProduct/{productId}”, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]

List<Product> GetProductDetails(string productId);

}

public class Product

{

public string ProductId { get; set; }

public string ProductName { get; set; }

public string ProductCost { get; set; }

}

Service Implementation

namespace WCFRESTServiceDemo

{

// NOTE: You can use the “Rename” command on the “Refactor” menu to change the class name “ProductService” in code, svc and config file together.

// NOTE: In order to launch WCF Test Client for testing this service, please select ProductService.svc or ProductService.svc.cs at the Solution Explorer and start debugging.

public class ProductService : IProductService

{

public List<Product> GetProductDetails(string productId)

{

Product objProduct = new Product();

List<Product> objProductData = new List<Product>();

objProduct.ProductId = productId;

objProduct.ProductName = “Laptop”;

objProduct.ProductCost = “1000 $”;

objProductData.Add(objProduct);

return objProductData;

}

Service Configuration
