The Windows Communication Foundation (previously codenamed "Indigo") is Microsoft's unified framework for building secure, reliable, transacted, and interoperable distributed applications.

WCF is the Windows Communication Foundation which is shipped along with Dot Net 3.0/3.5. User's having 2.0 framework can make use of WCF by installing the MS add-in component for WCF. WCF comes up as a replacement for Remoting and Web service in dotnet. The main feature of WCF is it's security. It can use the protocols like basice,wsHttp,tcp...wsHttp comes with default windows based security feature. WRT web services WCF works with the industry standard Contract based protocols. The componets WCF are data contract, Service Contract and the Service programme. WCF also supports many of the advanced WS-* Web service standards, which can provide rich Web service communication across platforms. WCF can be extended to use protocols other than SOAP to communicate with Web services, for example, Rich Site Summary (RSS). It is interoperable with WSE 3.0, System.Messaging, .NET Enterprise Services, and ASMX Web services.
This means that, with little or no change to code, existing applications that are built with these technologies can interoperate with WCF services. WCF contracts define the behavior of WCF services. They are created in code by service developers, and are exposed to clients in the service metadata. The five types of contracts:
Service Contracts
Operation Contracts
Data Contracts
Message Contracts
Fault Contracts
WCF is flexible because its services can be hosted in different types of applications. The following lists several common scenarios for hosting WCF services:
IIS
WAS
Self-hosting
Managed Windows Service

Windows Communication Foundation (WCF) is an SDK for developing and deploying services on Windows. WCF provides a runtime environment for your services, enabling you to expose CLR types as services, and to consume other services as CLR types. Although in theory you could build services without WCF, in practice building services is significantly easier with WCF. WCF is Microsoft’s implementation of a set of industry standards defining service interactions, type conversion, marshaling, and various protocols’ management. Because of that, WCF provides interoperability between services. WCF provides developers with the essential off-the-shelf plumbing required by almost any application, and as such, it greatly increases productivity. The first release of WCF provides many useful facilities for developing services, such as hosting, service instance management, asynchronous calls, reliability, transaction management, disconnected queued calls, and security. WCF also has an elegant extensibility model that you can use to enrich the basic offering. In fact, WCF itself is written using this extensibility model. The rest of the chapters in this book are dedicated to those aspects and features. Most all of the WCF functionality is included in a single assembly called System.ServiceModel.dll in the System.ServiceModel namespace.
