Samenvatting

'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
