Microsoft Windows Communication Foundation 4.0 Cookbook for Developing SOA Applications

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.

Capturing WCF request/response messages via Fiddler tool


When developing a WCF service, it is useful to capture the underlying messages of service operations (request and response). There are several different means for capturing service operation messages in WCF service applications.

In this recipe, we will introduce how we can use the Fiddler tool to capture the underlying messages issued by a WCF service (or client proxy) over the HTTP transport protocol.

How to do it...

Fiddler is a free web debugging tool that can help analyze network communication data over the HTTP transport layer such as the message/data issued by Internet Explorer, WinINet components, or .NET WebRequest components. Here we will demonstrate the detailed steps to use Fiddler to inspect the messages of a locally deployed WCF service application:

  1. Get the Fiddler tool installed on the local machine.

    First, we need to install Fiddler on the target machine where we want to capture messages. You can get the Fiddler tool...
