Justin Smith wcf HTTP Programming With WCF And The .NET Framework 3.5 hen it was first released as part of the Microsoft® .NET Framework 3.0, Windows® Communication Foundation (WCF) included a universal object model for Plain Old XML (POX) and SOAP messaging over a wide variety of transports. Because WCF also contains deep support for WS-* Web service standards, it is able to interoperate with other modern service platforms with relatively little difficulty. WCF in the .NET Framework 3.0 is highly extensible and includes solid manageability features like message logging, activity tracing, service throttling, instance management, and threading controls. WCF in the .NET Framework 3.5 builds on the extensibility points in the .NET Framework 3.0 to include first-class support for building services that adhere to the principles of the Web. This includes an easy-to-use HTTP programming model, JavaScript Object Notation (JSON) messaging capabilities, and a new syndication API that makes it easy to create and consume syndicated content. With this feature set, WCF is now the service platform of choice for connecting services to Web clients, whether they are ASP.NET AJAX controls, Silverlight™ clients, or even browsers. These features also work in partial trust scenarios (like ASP.NET medium trust) so you can host WCF services in widely available hosting environments. To round it all out, there’s also new tooling integrated into Visual Studio® 2008 that dramatically reduces the amount of time it takes to get a service up and running. 74 msdnmagazine Combining Web-centric communication with SOAP and WS-* standards into one service stack and object model is one of the features that makes WCF in the .NET Framework 3.5 so compelling. This means you can build a service that communicates within or across enterprise boundaries using SOAP and WS-*, and you can configure that same service to communicate externally using the syndication This article is based on a prerelease version of Visual Studio 2008.
