Description:

"For anyone involved in the .NET community, it's hard to not have heard of Christian Nagel. Christian is a true heavyweight of .NET in general, and Enterprise Services in particular. By taking a relatively trivial application and architecting it in a way that would allow it to scale without any rework, users will find that using the techniques employed in this book will be of benefit to virtually any company that is running distributed or enterprise applications."

—William G. Ryan, Microsoft MVP, Senior Software Developer, TiBA Soutions, LLC

"Whether you are a seasoned architect or a new developer, distributed application development can be difficult, since it covers such a wide range of complex technologies. Until now there was precious little in the way of guidance—let alone a consolidated reference. Christian has provided that reference and more—going from the individual technologies to the big picture on how to architect and develop scalable distributed applications. Technical goodness through and through!"

—Clayton Burt, Managing Partner, Onzo, LLC

"Making the transition to distributed application architecture introduces many issues in security and deployment and requires a new way of thinking about events, transactions, and messaging. This book shows developers and architects alike how to use .NET Enterprise Services to create robust, secure, and maintainable applications in a distributed environment. This book is an excellent guide to the sometimes overwhelming field of .NET Enterprise Services."

—Brian Davis, Director of Software Development, InfoPro Group, Inc., Co-Creator, KnowDotNet.com

Enterprise Services with the .NET Framework is the only book that experienced .NET developers need to learn how to write distributed, service-oriented applications. Filled with clear examples in C# (with Visual Basic .NET examples available on the Web), this book will quickly get you up to speed on building distributed applications with serviced components. You'll also learn about Indigo, Microsoft's next-generation technology for building distributed applications, and how it compares to Enterprise Services.

Microsoft Regional Director, MVP, and veteran author Christian Nagel introduces and clearly explains the four major services included in Enterprise Services: Automatic Transactions, Queued Components, Loosely Coupled Events, and Role-Based Security. From his in-depth coverage, you'll learn

  • How to create a serviced component, how serviced objects are activated, and how to use the different kinds of object contexts

  • How to manage concurrency and synchronization for serviced components to achieve optimal performance and data integrity

  • How to integrate COM components with the .NET Framework

  • How to use serviced components over a network with DCOM, SOAP Services, and ASP.NET Web services

  • How to use .NET Enterprise Services transactions to achieve Atomicity, Consistency, Isolation, and Durability

  • How to build a compensating resource manager to allow your own resources to participate in Enterprise Services transactions

  • How to maintain application state in a client application, in a serviced component, in shared properties, or in a database

  • How to create and use Loosely Coupled Events using COM+

  • How to secure a distributed solution using authorization, authentication, impersonation, and confidentiality

  • How to deploy and configure Enterprise Services applications

商品描述(中文翻譯)

描述:
對於.NET社群的任何參與者來說,很難不知道Christian Nagel。Christian是.NET的重量級人物,尤其在企業服務方面更是如此。通過將一個相對簡單的應用程序架構成可以無需重新工作即可擴展的方式,使用本書中所使用的技術將對任何運行分佈式或企業應用程序的公司都有益處。

"無論您是一位經驗豐富的架構師還是一位新手開發人員,分佈式應用程序開發都很困難,因為它涵蓋了如此廣泛的複雜技術。直到現在,幾乎沒有任何指導,更不用說統一的參考資料了。Christian提供了這樣的參考資料,並且更進一步,從個別技術到如何架構和開發可擴展的分佈式應用程序的整體圖景。從頭到尾都是技術上的好東西!"

"轉向分佈式應用程序架構會引入許多安全性和部署問題,並需要以新的方式思考事件、事務和消息。本書向開發人員和架構師展示如何使用.NET企業服務在分佈式環境中創建強大、安全和可維護的應用程序。本書是一本對於.NET企業服務這個有時令人不知所措的領域的優秀指南。"

".NET Framework的企業服務是經驗豐富的.NET開發人員學習如何編寫分佈式、面向服務的應用程序所需的唯一一本書。本書以C#為例(網上提供Visual Basic .NET的示例),將快速使您掌握使用服務組件構建分佈式應用程序的技能。您還將了解到Indigo,微軟用於構建分佈式應用程序的下一代技術,以及它與企業服務的比較。"

微軟區域總監、MVP和資深作者Christian Nagel介紹並清晰解釋了企業服務中包含的四個主要服務:自動事務、佇列組件、鬆散耦合事件和基於角色的安全性。從他深入的介紹中,您將學到:

如何創建服務組件,服務對象如何激活,以及如何使用不同類型的對象上下文
如何為服務組件管理並發性和同步,以實現最佳性能和數據完整性
如何將COM組件與.NET Framework集成
如何使用服務組件通過DCOM、SOAP服務和ASP.NET Web服務在網絡上使用
如何使用.NET企業服務事務實現原子性、一致性、隔離性和持久性
