.NET provides various options for creating services under .NET Framework. Before WCF, ASP.NET Web Services are used to ceate service in .NET Framework. Now WCF is the latest programming model for building and developing service-oriented application. WCF allows applications to communicate with each other in distributed environment.
WCF stands for Windows Communication Foundation. It is Microsoft's latest technology that enables applications in a distributed environment to communicate with each other. WCF is Microsoft's unified programming model for building service-oriented applications.
There are two ways : Proxy and Channel Factory; to create a WCF Client or calling a WCF Service. In this article, I am going to expose the difference between Proxy and Channel Factory.
WCF manage session by creating the instance of the service class. These created instance(s) handle the incoming service request.

WCF stands for Windows Communication Foundation.

It enables developers to build secure, reliable, transacted solutions that integrate across platforms and interoperate with existing.
