This book is about application architecture, design, and development in .NET using objectoriented
concepts. The focus is on business-focused objects called business objects, and how to
implement them to work in various distributed environments, including web and client/server
configurations. The book makes use of a great many .NET technologies, object-oriented design
and programming concepts, and distributed architectures.
The first half of the book walks through the process of creating a framework to support
object-oriented application development in .NET. This will include a lot of architectural concepts
and ideas. It will also involve some in-depth use of advanced .NET techniques to create
The second half of the book makes use of the framework to build a sample application with
several different interfaces. If you wish, it’s perfectly possible to skip the first half of the book and
simply make use of the framework to build object-oriented applications.
One of my primary goals in creating the CSLA .NET framework was to simplify .NET development.
Developers using the framework in this book don’t need to worry about the details of
underlying technologies such as remoting, serialization, or reflection. All of these are embedded
in the framework so that a developer using it can focus almost entirely on business logic and
application design, rather than getting caught up in “plumbing” issues.
