No, I haven't written a book, well, not just yet.  Anyhow, so far in the Domain Driven Design world, we have a few references of how to do Domain Driven Design.  These books are an invaluable resource for doing DDD, but at the end of the day, they don't have as many end-to-end solutions.  The current books/bibles on DDD are:
Some of these books are great, but left me wanting at a complete end to end solution.  Also, The discussion of Value Objects versus Entities was not very well covered in the Jimmy Nilsson book, which left me a bit frustrated.  So, there is definitely more material needed on the subject.

Tim McCarthy has started a book called .NET Domain-Driven Design with C# : Problem - Design - Solution which is due out in April of this year.  This definitely looks promising as an end to end scenario of how to do DDD in the context of .NET solutions.  Tim has also been gracious enough to host the code example from his book on CodePlex, which can be found here.  Slides are also available from his presentations on "Building an Offline Smart Client using Domain Driven Design Principles".

Here's the description of the book from the site:

This first technical title of its kind, this is a revolutionary book for the object oriented developer. It takes the reader through the intense process of building a real-world application using Domain-Driven Design principles implemented in C# 3.0 (.NET Framework 3.5). The reader is introduced to a business domain of a real-world Construction Administration application for an architecture firm. The application is ma critical, legacy MS Access application that has outgrown MS Access and is ready to become a full-fledged enterprise application. In each chapter, the relevant part of the domain is modeled out via diagrams and code. The application is built using C#, Windows Presentation Foundation, and other Microsoft technologies and best practices. The main focus of the book is on designing and implementing the domain model and all of the supporting patterns and framework that are built in support of the domain model. The emphasis is on these theories in action through the working application, not on the tools used. The main goal is to show how to take a set of requirements and user scenarios and apply Domain-Driven Design principles to the requirements in order to create a domain model that satisfies both the user requirements and the system requirements.  Various patterns are introduced along the way in order to aid with certain activities such as adapting the domain model to the user interface, synchronizing data between the client and the server, validation, mapping, etc. Although this particular application is a WPF application, most of the design patterns introduced and applied in the book can be used on other types of applications, such as web applications, web services, etc.

With the Problem-Design-Solution promise and approach, the chapters are broken down into their own modules where the intent is to take the reader through the process from beginning to end while building a complete project with each chapter module. Each chapter establishes the problem, what the reader wants to do, and why it is important, and then what factors and restrictions need to be taken into account. Next the chapter covers how the programmer will solve the problem with an adequate solution that will provide only the best results. Finally, the developer produces code and other materials to better realize the design and solution to the problem. This part of the chapter is where the reader gets hands-on practice at creating code that builds applications.

Like I said above, it should be an interesting book when it comes out.  I'll do a review once it does as I'm hoping for the best! Posted on Monday, January 14, 2008 9:19 AM C# , Domain Driven Design | Back to top
