Webservices & WCF

Web Services initiated SOA application development, which is one of the most influential design pattern .A web service is a standard platform for building interoperable distributed applications. It allows you as a developer, to interact with other information providers without worrying about what they are running either at the backend or even their front-end.

Windows Communication Foundation (or WCF) is an application programming interface (API) in the .NET Framework for building 2nd generation Service Oriented Applications. WCF is designed in accordance with service oriented architecture principles to support distributed computing where services are consumed by consumers. Clients can consume multiple services and services can be consumed by multiple clients.
