Windows Communication Foundation
Windows Communication Foundation (WCF) is a framework for building service-oriented applications. It uses endpoints, addresses, bindings, and contracts to define services and allow clients to access them. The document discusses WCF basics like service contracts, hosting services, and standard bindings. It also mentions sessions, instances, transactions, concurrency, and security in WCF. The document promotes the author's blog and provides links for learning more about WCF instancing, transactions, and examples. It ends by inviting questions and providing contact information.

Editor's Notes
- #4 1980s - Object Oriented1990s – Component Based (dynamic loading)2000s – Service Oriented (doing messages.. That is when we think about distributed envirountemnt)WCF – is unified framework for building service oriented applications.Windows Communication Framework – what the HECK does that mean? WCF, WPF, WF, Microsoft’s merry-go-round of acronyms seems to have experienced exponential growth with the releases of 3.0 and 3.5. Is it all just marketing hype? Fortunately, no!WCF was first released in 3.0, and lives in its most current form in 3.5. WCF puts a wide swath of .NET service technologies all under the same roof. Windows Communication Framework utilizes declarative and configuration-driven programming to enable you to define multiple endpoints against the same code. In a lot of ways, it is very much a hybrid of legacy ASMX, WSE, Web Service Enhancements and remoting all in one.Juval Lowy very rightly describes WCF as “plumbing,” and as “an SDK for developing and deploying services on Windows.”Replaces ASMX services.Web Services Enhancements (WSE) is an add-on to the Microsoft.NET Framework which includes a set of classes that implement additional WS-*Web servicespecifications chiefly in areas such as security, reliable messaging, and sending attachments. [1] Web Services are business logic components which provide functionality via the Internet using standard protocols such as HTTP. Web services communicate via either SOAP or REST messages. WSE provides extensions to the SOAP protocol and allows the definition of custom security, reliable messaging, policy, etc.All the COM+ services that are available today are available to .NET and COM objects. Some of these services include, transactions, object pooling and construction strings, JIT, synchronization, role-based security, CRM and BYOT.
