WCF - Features Interoperability


WCF - Features Interoperability

  • WCF extends its support for both Microsoft based technologies.
  • This WCF tutorial will focus more on this interoperability feature.

Interoperability of WCF :

  • WCF is capable of 
    • interacting with variety of services exposed over internet.
    • It is used to communicate with programs written in different languages.
    • Based on different operating systems. 
  • WCF uses Web services technologies introduced by the WS-* specifications. 
  • These specifications is the part of Organization for the Advancement of Structured Information Standards (OASIS).
  • Below are list of such scenarios for interactions:
    • Interacting with WCF-based applications: 
      • running on the same Windows machine in a different process.
      • running on another Windows machine.
    • Interacting with programs based on other technologies: 
      • Those programs follow web service standards. 
      • They are running on the same machines with Windows.
      • They are running on machines with other operating systems. This is depicted below:


WCF’s Interoperability

WCF Specifications : 

  • WCF interactivity is considered as a stable communication methodology with measures shown in the below . 


WCF specifications

Messaging : 

  • SOAP and HTTP is based on  Web Service messaging which enhanced by WS-Addressing and MTOM.
  • WS-Addressing introduces additions to the SOAP header to discontinue its dependency on HTTP protocol for message communications by using MTOM.
  • The Message Transmission Optimization Mechanism (MTOM) outlines an enhanced communication format and XML-binary Optimized Packaging (XOP) for SOAP messages.

Metadata : 

  • The Web Services Description Language (WSDL) with standard language specification for Web Services is enhanced by WS-Policy, WS-Metadata Exchange and WS-Discovery.
  • WS-Policy permits description of more lively aspect of a service’s performance.
  • WS-Metadata Exchange permits a client to demand explanations about WSDL and its policies, via SOAP messages.
  • The WS-Discovery protocol enables services to be identified at runtime in an interoperable manner.

Security : 

  • WS-Security, WS-Trust and WS-Secure Conversation provide enhancements to SOAP messages in order to deliver authentication, data reliability, data confidentiality and other related security features.

Reliability : 

  • WS-Reliable Messaging defines enhanced reliable end-to-end communication for one or more SOAP message transfers.

Transactions : 

  • WS-Coordination and WS-AtomicTransaction permits two-phase commit transactions with SOAP-based message exchange.
