What is WCF ? Windows Communication Foundation is

Microsoft's next-generation programming platform and runtime system for building, configuring and deploying network-distributed services

WCF Unification





WCF Basics - ABC "ABC" is the key to understand how a WCF

service is composed:

"A" stands for Address: Where is the service?

"B" stands for Binding: How do clients talk to the service?

"C" stands for Contract: What can the service do for a client?





Data Contract [DataContract] public class AdnMaterial { [DataMember] public string Name { get; set; } [DataMember] public double Price { get; set; } [DataMember] public string Manufacturer { get; set; } }





Service Contract [ServiceContract] public interface IMaterialSrv { [OperationContract] AdnMaterial[] GetMaterials(); [OperationContract] AdnMaterial GetMaterial( string materialName); [OperationContract] bool PostMaterial( AdnMaterial material); }





Implementing Services

public class MaterialSrv : IMaterialSrv { public MaterialSrv() { //Constructor... }

public AdnMaterial[] GetMaterials() { //Implementation... }

//Implementation other methods... }





Service bindings

A binding binds a service contract implementation to an address.

This includes:

Choosing an appropriate transport protocol

Choosing how messages are encoded

Defining how security works





Hosting a Service

The following options are available to host a WCF Service:

Self-hosting in any managed .NET applicationWinform, WPF, console Application, …

Hosting in a Windows service

Hosting in IISASP.NetDirect Hosting





WCF Demo





HTTP Requests

World Wide Web (WWW) Web of resources Resources reference each other Resources can be of many types

(e.g., documents, images, services, html pages)

URI identifies resources (Uniform Resource Identifier)

HTTP used to access resources 9 methods (a.k.a. verbs): GET, PUT , POST , DELETE , … HEAD, OPTIONS, TRACE, CONNECT, PATCH

SOAP

SOAP stands for Simple Object Access Protocol

Protocol for exchanging structured information through Web Services

Relies on XML for its message format, and Application Layer protocols like HTTP or SMTP for message transmission





REST

REST stands for Representational State Transfer

REST is an architectural style that exploits HTTP protocol

Provides an easier way of data access comparing with SOAP

Good solution for interoperability between web services and mobile platforms or browsers





REST Web Services Why REST?

REST is a lightweight alternative to SOAP

SOAP:

SOAP

REST

<?xml version="1.0"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/12/soap-envelope"> <soap:Body pb="http://www.adesk.com/memberdb"> <db:GetDeveloperDetails> <db:DeveloperID>12345</db:DeveloperID> </db:GetDeveloperDetails> </soap:Body></soap:Envelope>

http://www.adesk.com/memberdb/DeveloperDetails/12345





SOAP vs RESTSOAP

Supports only GET and POSTAll data is in the xml message

Resource to accessFunction to execute

REST

Uses all HTTP verbs: GET, POST, PUT, DELETE, …Resource is identified by URIFunction is identified by the HTTP verb





JSON JSON (JavaScript Object Notation) is a

lightweight data exchange format

JSON is a text format easy for humans to read and write and fast for machines to parse and generate

One of the most popular exchange format in web services at the moment





JSON vs XML { "Manufacturer":"ADN", "Name":"Steel", "Price":"100.0" }

<?xml version="1.0" encoding="UTF-8" ?> <Manufacturer>ADN</Manufacturer> <Name>Steel</Name> <Price>100.0</Price>





Adding REST Support in WCF [ServiceContract] public interface IMaterialSrv { [OperationContract] [WebInvoke( Method = "GET", UriTemplate = "/Material/{materialName}", ResponseFormat = WebMessageFormat.Json)] AdnMaterial GetMaterial(string materialName); [OperationContract] [WebInvoke( Method = "POST", UriTemplate = "/Material", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] bool PostMaterial(AdnMaterial material); }
