Why to use WCF? or What are the advantages of using WCF?

Answer

• Service Orientation is one of the key advantages of WCF. We can easily build service-oriented applications using WCF.
• If compared with ASMX web services, WCF service provides reliability and security with simplicity.
• As oppose to .NET Remoting, WCF services are interoperable.
• Different clients can interact with same service using different communication mechanism. This is achieved by using service endpoints. A single WCF service can have multiple endpoints. So, developer will write code for service once and just by changing configuration (defining another service endpoint), it will be available for other clients as well.
• Extensibility is another key advantage of WCF.  We can easily customize a service behavior if required.
