This book is a translation of Lhotka's industry-standard title, Visual Basic.NET Business Objects, into the language of C#. Rockford Lhotka's ideas continue to be extremely influential in all programmer circles of any language, but most naturally it will be C# developers over the next couple of years at least who will most likely be involved in the kinds of programming projects and architectures that Lhotka discusses. This book will benefit you! This book contains the author's Component- based, Scalable, Logical Architecture (CSLA .NET), an object-oriented framework that can act as the foundation for a diverse range of enterprise applications, and which readers are free to examine, use, and modify.
