WCF from the web developer
- 1. WCF for the web developer Florin Cardașim, caf@rms.ro twitter: @cardasim, @CodeCampIasi RomSoft, www.rms.ro Iași, 8th of May 2010
- 2. Agenda WCF today: an overview WCF Services for the WEB 2.0 SOAP & REST WCF Data Services
- 3. WCF Today Programming Model SOAP Services WEB HTTP Services Data Services RIA Services Workflow Services Service Model Data Contract Service Contract Service Behavior Channel Model Formats (XML, JSON, Atom…) Transports (HTTP, TCP, IPC, MSMQ…) Protocols (SOAP, HTTP, Open Data Protocol,…)
- 4. WCF Architecture - Channels WCF Service WCF Client Channel A Channel A Channel B Channel B Channel C Channel C Transport Channel Transport Channel HTTP, TCP, MSMQ, etc.
- 5. WCF Architecture - Bindings WCF Service [ServiceContract] interface IExampleB { . . .} [ServiceContract] interface IExampleA { . . .} Binding 3 Binding 1 Binding 2 Transactions Transactions RM Security Security Transport HTTP Transport HTTP Transport TCP
- 6. Demo: WCF Services for the WEB 2.0
- 7. What is SOAP SOAP = Simple(?!!) ObjectAccessProtocol =protocol, =standards advanced features: security, reliable messaging, transactions transport neutrality (http, tcp, ipc, msmq …) uses POST when used over HTTP roots in enterprise applications
- 8. SOAP-HTTP bindings wsHttpBinding SOAP 1.2 Transaction Flow Reliable Session basicHttpBinding SOAP 1.1 Symmetric Security HTTP Transport (Text Message Encoding) HTTP Transport (Text Message Encoding)
- 9. SOAP & WS-* MEX Policy WSDL SEC: Kerberos, Username, X.509, SAML Secure Conversation, Federation, Trust RM: Reliability, Reliable Messaging TRAN: BussinessAct, Atomic, Coordination Messaging: SOAP, Addressing, MTOM, Transfer, Discovery… XML: XML, XSD, Digital Signature, Encryption Transport: HTTP/S, TCP, SMTP, UDP…
- 10. A SOAP request WCF Client WCF Service POST /AccountAccess/Accounts.svc Host: www.quickbank.com SOAPAction: GetBalance … <soap:Envelopexmlns:soap= … <soap:Body> <GetBalancexmlns= … <Account>2</Account> </GetBalance> </soap:Body> </soap:Envelope> Account 1 Account 2 Account 3
- 11. What is REST REST = REpresentationalState Transfer ! protocol, ! format, ! standard = architectural style everything is a resource: Account, Balance … address: www.quickbank.com/Accounts/2 uniform interface: HTTP GET, POST, PUT, DELETE roots in WEB facing services (for example Google Search)
- 12. A REST request WCF Client WCF Service GET www.quickbank.com/Accounts/2 Account 1 Account 2 Account 3
- 13. Demo: Twitter REST Service Formats: XML, JSON RSS, ATOM webHttpBinding HTTP Transport (Web Message Encoding)
- 14. SOAP & REST
- 15. When to SOAP? When to REST? Exposing data OR operations? Need for WS-*? Who will be using your service? What are you/your developers comfortable with? REST seems to be preferred in the clouds: Amazon S3 Windows Azure Google …
- 16. OData: WCF Data Services Open Data Protocol REST-based protocol for CRUD-style operations Based on AtomPub Formats: Atom, Xml, JSON DEMO
- 18. SQL Azure
- 19. SharePoint 2010
- 21. IBM WebSphere
- 23. Please fill the evaluation formThank you very much! Florin Cardașim, caf@rms.ro twitter: @cardasim, @CodeCampIasi RomSoft, www.rms.ro Iași, 8th of May 2010
- 24. Demo: REST in .NET 4.0 Caching Automatic format selection REST Starter Kit: Client API Paste as Xml

- SOAP (basic-profile, ws-*)REST (xml, json, atom/rss)Why SOAP? Why REST?
- Core Services: SOAP over any transport channelOperation-centric servicesWS-* standardsWeb HTTP Services: REST over HTTPWEB Facing services over HTTPXml/JSON/ATOM/RSSWCF Data Services (ADO.Net Data Services)Exposing data over Open Data Protocol (REST interface)WCF RIA Services (.NET RIA Services)Building end-to-end Silverlight applicationWCF Workflow ServicesLong running, durable operations or where the specification and enforcement of operation sequencing is important
