  2. Getting Started • Windows Communication Foundation (WCF) • http://msdn.microsoft.com/en-us/library/ms731082.aspx • Cloud Hosting Providers • http://www.windowsazure.com • http://aws.amazon.com

  3. WCF Web ServicesMigrate your Application logic to the cloud…

  4. What is WCF ? • Windows Communication Foundation is Microsoft's next-generation programming platform and runtime system for building, configuring and deploying network-distributed services (Source MSDN)

  5. WCF Unification

  6. 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?

  7. Data Contract [DataContract] publicclassAdnMaterial { [DataMember] publicstring Name { get; set; } [DataMember] publicdouble Price { get; set; } [DataMember] publicstring Manufacturer { get; set; } }

  8. Service Contract [ServiceContract] publicinterfaceIMaterialSrv { [OperationContract] AdnMaterial[] GetMaterials(); [OperationContract] AdnMaterialGetMaterial( stringmaterialName); [OperationContract] boolPostMaterial( AdnMaterialmaterial); }

  9. Implementing Services publicclassMaterialSrv : IMaterialSrv { publicMaterialSrv() { //Constructor... } publicAdnMaterial[] GetMaterials() { //Implementation... } //Implementation other methods... }

  10. 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

  11. Hosting a Service • The following options are available to host a WCF Service: • Self-hosting in any managed .NET application Winform, WPF, console Application, … • Hosting in a Windows service • Hosting in IIS ASP.Net Direct Hosting

  12. WCF Demo

  13. 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

  14. 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

  15. 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 betweenweb servicesand mobile platforms or browsers

  16. REST Web Services Why REST? REST is a lightweight alternative to SOAP SOAP: <?xmlversion="1.0"?> <soap:Envelopexmlns:soap="http://www.w3.org/2003/12/soap-envelope">  <soap:Bodypb="http://www.adesk.com/memberdb">   <db:GetDeveloperDetails>    <db:DeveloperID>12345</db:DeveloperID>   </db:GetDeveloperDetails>  </soap:Body> </soap:Envelope> SOAP REST http://www.adesk.com/memberdb/DeveloperDetails/12345

  17. SOAP vs REST SOAP • Supports only GET and POST • All data is in the xml message Resource to access Function to execute REST • Uses all HTTP verbs: GET, POST, PUT, DELETE, … • Resource is identified by URI • Function is identified by the HTTP verb

  18. 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

  19. 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>

  20. Adding REST Support in WCF [ServiceContract] publicinterfaceIMaterialSrv { [OperationContract] [WebInvoke( Method = "GET", UriTemplate = "/Material/{materialName}", ResponseFormat = WebMessageFormat.Json)] AdnMaterialGetMaterial(stringmaterialName); [OperationContract] [WebInvoke( Method = "POST", UriTemplate = "/Material", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] boolPostMaterial(AdnMaterialmaterial); }
