Written by Microsoft software legend Juval Lowy, Programming WCF Services is the authoritative introduction to Microsoft's new, and some say revolutionary, unified platform for developing service-oriented applications (SOA) on Windows. Relentlessly practical, the book delivers insight, not documentation, to teach developers what they need to know to build the next generation of SOAs. After explaining the advantages of service-orientation for application design and teaching the basics of how to develop SOAs using WCF, the book shows how you can take advantage of built-in features such as service hosting, instance management, asynchronous calls, synchronization, reliability, transaction management, disconnected queued calls and security to build best in class applications. Programming WCF Services focuses on the rationale behind particular design decisions, often shedding light on poorly-documented and little-understood aspects of SOA development. Developers and architects will learn not only the "how" of WCF programming, but also relevant design guidelines, best practices, and pitfalls. Original techniques and utilities provided by the author throughout the book go well beyond anything that can be found in conventional sources. Based on experience and insight gained while taking part in the strategic design of WCF and working with the team that implemented it, Programming WCF Services provides experienced working professionals with the definitive work on WCF. Not only will this book make you a WCF expert, it will make you a better software engineer. It's the Rosetta Stone of WCF.

Built on the Microsoft .NET Framework and around the Web Services architecture, Windows Communication Foundation (formerly known as Indigo ) is a technology for building and running connected systems providing reliable and secure transactional messaging.This book, targeted for developers currently developing applications using the .NET Framework and related technologies, will discuss the new Windows Communication Foundation technologies available from Microsoft, the next generation of configuring and deploying network-distributed services. Some of the topics covered include:· Addresses· Binding· Contracts· Clients· Services· Security· Deployment· Management· Hosting

Pro WCF 4.0: Practical Microsoft SOA Implementation is a complete guide to Windows Communication Foundation from the service-oriented architecture (SOA) perspective, showing you why WCF is important to service-oriented architecture and development. This book provides deep insight into the functionality of WCF, which shipped with .NET 4.0-like service discovery, routing service, simplified configuration, and other advanced features. Included in this title are informative examples that will aid the reader in understanding and implementing these important additions. This book also covers the unified programming model, reliable messaging, security, and the peer-to-peer programming model. You'll also learn how to move your current .NET remoting and web service applications to WCF, and how to integrate those applications with WCF 4. This book offers genuine insight into solving real enterprise problems using WCF and .NET 4.0.

The current volume aspires to add to previous research on the connection between writing and language learning from a dual perspective: It seeks to reflect current progress in the domain as well as to foster future developments in theory and research. The theoretical postulations contained in Part I identify and expand in novel ways the diverse lenses through which the varied, multi-faceted dimensions of the connection between writing and language learning can be explored. The methodological reflections put forward in Part III signal theoretically-grounded and pedagogically-relevant paths along which future empirical work can grow. The empirical studies reported in Part II illuminate the myriad of individual, educational, and task-related variables that (may) mediate short-term and long-term language learning outcomes. These studies examine diverse forms of writing, performed in varied environments (including pen-and-paper and digital writing), conditions (writing individually and/or collaboratively), and instructional settings (academic settings – including secondary school and college level institutions – as well as out-of-school contexts).
