Description
.NET Enterprise Services is a managed class in COM+ that allows developers to build scalable applications quickly and easily, by automated business solutions, rather than writing code from scratch. .NET Enterprise Services are delivered as a part of the Windows 2003 operating system, and also work with Web Services. While Microsoft is currently encouraging developers to build distributed applications using Enterprise Services, there is little information available. Enterprise Services with the .NET Framework responds to the needs of all developers looking to build and automate business solutions using the .NET Framework. It is the only book that clearly explains what .NET Enterprise Services are and how to use them to build effective distributed business applications. It presents the big picture of .NET Enterprise Services using clear explanations and practical examples. It discusses the architecture using straightforward language and demonstrates how to use all of the Enterprise Services technologies to develop scalable distributed applications.
