Overview of this book

The Windows Communication Foundation 4.0 (WCF 4.0) is a .NET-based application programming interface for building and running connected systems. It enables secure and reliable communication among systems within an organization or across the Internet. This book deals with the difficult issues faced by a .NET developer while working with WCF.WCF 4.0 is a communications infrastructure that unifies a broad array of distributed systems' capabilities in a composable, extensible architecture that supports multiple transports, messaging patterns, encodings, network topologies, and hosting models. This book is a collection of focused real-world recipes and covers basic recipes on topics such as working with contracts to more advanced topics such as extending WCF runtime. By the end of this book you will have valuable information that helps transform the potentially unproductive habits of .Net developers who work with WCF.This book will take you through many concepts starting with complete support for contract-related design for WCF service development. You will learn to use WCF's built-in feature for building various service endpoints. Service hosting and configuration are important areas for building WCF services, especially at the service deployment stage, and are detailed in this book. You will find it easy to work with WCF client proxy generation and metadata publishing and discovery when you go through recipes such as customizing auto-generated service proxies.The author then discusses the exchange of data in WCF service operation features, related to WCF data serialization. You will discover some useful tips for security in WCF service development and built-in features for developing concurrency control for your services built upon it.One big plus is that you will learn to extend the existing WCF framework to achieve advanced functionality. You will find a dedicated chapter for RESTful and AJAX-enabled service development. Moving on, you will find several useful WCF service interoperability cases, which are important for a distributed service development platform. Towards the end of this book you will find some handy and useful diagnostic methods for troubleshooting.

Transferring binary data with MTOM encoding

For Web Services/WCF services that use SOAP XML as the natural message format, binary data in service operations will be transferred as the Base64-encoded string over the transport layer. This is not quite efficient for binary data transfer, as the encoded Base64 string will increase the data size compared to raw binary bytes. Fortunately, WCF supports the MTOM message encoding that can help transfer binary data as their raw bytes within a standard SOAP envelope.

In this recipe, we will use a sample service to demonstrate the steps necessary for applying MTOM message encoding for WCF service endpoints.

Getting ready

Most of the HTTP-based WCF built-in bindings support the MTOM encoding format. A detailed list is provided in the MSDN WCF Binding description at:

System-Provided Bindings
