 Nice book, here is the Table of ContentsDec 23, 2008
By Lerxst
This book seemed really promising from the title and mainly its author (Dino Esposito), who is one of the best .NET writers out there. It took me a while to buy it though, because for weeks I tried in vain to find its table of contents, to know exactly what I was buying. Having failed at finding one, I decided to just take a chance and buy it anyway, and I don't regret, it is a good book.
I would say the target audience is intermediate to senior developers who are getting into software architecture, or architects who work on a database-centric way and want to get an update to the current buzzwords, such as domain model pattern, repositories, services, AOP, POCO, OR/M, DDD etc. This book does not try to be a definitive source on any of those topics, but more like an introduction and a reference; the authors make a good job at pointing for resources for those who want to get more dense information.
Books like Martin Fowler's "Patterns of Enterprise Application Architecture", the GoF classic Design Patterns book and Eric Evan's "Domain-Driven Design" are mentioned dozens of times, so people who have already read those books may not have lots of new stuff to see here, unless they are looking for a lighter reference or want to see how some of those ideas can be applied on .NET.
So, for those like me who have spent a few days on Google trying to find out the book's ToC, here is a summarized version, with some of the topics covered in parenthesis:
Part 1 - Principles
1 - Architects and Architecture Today (software life cycle, agile methodologies etc)
2 - UML essentials (UML models and usage, use-case diagrams, class diagrams, sequence diagrams)
3 - Design Principles and Practices (OOD, AOP)
Part 2 - Design of the System
4 - The business layer (transaction script pattern, table module pattern, active record pattern, domain model pattern, DDD)
5 - The service layer (service layer pattern, remote façade pattern, adapter pattern, SOA, AJAX service layer for rich web frontends)
6 - The data access layer (plugin pattern, Inversion of Control, data context, query services, concurrency, lazy loading, OR/M, stored procedures, dynamic SQL)
7 - The presentation layer (MVC, MVP, presentation model pattern, choosing a UI pattern, MVP in web presentations, MVP in Windows presentations)
8 - Final thoughts

This book will not leave my side... until the 2nd edition...Dec 04, 2008
By T. Anderson
This book does a great job of putting architecture into a view that .NET developers and architects can relate to.
The book covers design principles and patterns, and then relates them to each layer of a traditional layered system. It includes business, services, data access, and presentation layers. The authors include several different patterns for each layer and discuss the pros and cons of each.
The book focuses on the technical aspects of .NET architecture. It does not cover the soft skills need to be an architect, or cover the customer facing skills need to communicate with the business stakeholders. You won't find much on process either, just an overview. These missing topics have not taken away from the book, they have made it a stronger book. There are plenty of resources on how to execute the soft skills and architecture process. This book concentrates on how to communicate with the development team through solid design and well known patterns and principles.
This is a must read for all architects, no matter what your skill set is.
A .NET developer looking to move into architecture should make this book their first stop on a long journey. This will definitely get you off to a very strong start.
This book will not leave my side... until the 2nd edition...

If you want to know the current .NET architectural trends, this is a must readJan 01, 2009
By James Ashley
It is a misconception that architecture is a fully understood field. Like the rest of us in the relatively young discipline of software development, architects are making their way along with rules of thumb, buzzwords and trends, too, and doing their best to tie them all together.
Microsoft has always been a bit lacking when it comes to providing guidance for developing complex software. The alt.net crowd promised to fill in this lacuna, and even promoted itself in terms of filling in the blanks that Microsoft leaves in its technology offerings. However the results have been, I think, that the contemporary architect simply has more pieces to try to put together, and even more things to try to figure out.
Dino Esposito, in "Architecting Applications for the Enterprise", tries to make sense of this technical jigsaw puzzle by building on top of the core architectural concepts of layering and decoupling applications. He then takes these principles forward by seeing how the newest technologies and techniques -- WPF, WCF, Windsor, NHibernate, Entity Framework, MVP, MVC, etc. -- can fit together to form a mature enterprise application.
In many ways he cuts through much of the hype and provides insights into why you might want to use these technologies. He is comprehensive in treating each of the various Microsoft and non-Microsoft tools soberly, explaining the pros and cons of each.
Best of all, he tries to consolidate in his appendix all of his insights into a core set of architectural principles, one of which he reiterates throughout the book: the job of the architect is to reduce complexity, not increase it. It sounds simple, but many architects tend to forget this.
Mr. Esposito's final product is a synoptic view of the current state of software architecture. If you want to know what is currently thought of as best practices in enterprise architecture, then you need to read this book. It will either give you an idea of where you need to be, if you are just starting out, or reassure you that you are on the right track, if you have been following the trends of the past two or three years.
The only weakness I found in the book is perhaps the problem that these various tools don't always fit together nicely. For instance, I'm doubtful that ORMs really makes sense anymore if we decide to place them behind service layers. SOA and ORMs rose out of really different architectural problems, and provide somewhat incompatible solutions. Likewise, while the MVP pattern is very nice (we are curently using it on an enterprise project), it tends to break down when you attempt to apply it to anything complex, such as an object graph with more than two or three levels of dependent objects.
The book also recommends using interfaces extensively in order to promote testability, but on looking a little closer, this appears to be tied to a specific tool, Rhino Mock, which requires interfaces to be useful, rather to any particular architectural principle -- for instance, TypeMock doesn't require interfaces, but of course it also isn't free. Should your architecture really be tied to a tool in this way, or would it be better to find tools that support your architecture?
I tend to think, however, that this is a weakness in the current state of architecture rather than of Mr. Esposito's work. The truth is we are all trying to work this out together, and we are currently only mid-stream in our journey toward mature application architectures.
"Architecting Applications for the Enterprise" fortunately brings us all to the same point, as software professionals, and allows us to see the horizon for our collective next step forward.

 Gets better...Apr 03, 2010
By S. Thompson
"the laowai guy"
This book is divided into two halves - Principles and System Design. The first half of this book is like a computer science course in system analysis and design. In my opinion fairly boring really, unless you are completely new to the subject. It does create a context for the rest of the book and though and even though it was a bit of a chore, I did find some interesting tidbits of information in part 1. The second half of the book moves from the theory of architecting software into the implementation with comprehensive coverage of all the different logical tiers of a system - presentation, service, business and data. It also discusses the different architectures that can be applied depending on the technologies used (forms, web, ria ect). This is where this book really shines. For me the further I got into the book the more I liked it. The writing style is conversational which make this book an easy read, although occasionally the author loses the plot a little, taking half a page to cover a point that could be covered succinctly in one line or two line.
By the end of this book I kind of liked it, although having said that it doesn't really offer anything new that hasn't been covered in other books, apart from the fact that the focus is on .Net technologies. For me I don't think this book offers too much to experienced developers, especially those with a lot of experience using .Net. Also for general software architectural principals there are better books around. Being fairly new to the .Net framework I brought this book primarily for an overview of .Net technologies that could be used in architecting applications and the best practices in applying them. In that sense this book is pretty good.
So if you're new to architecting software, or want an overview of .Net technologies and frameworks read this book. For experienced .Net folks I wouldn't bother, as this book probably won't teach you too much, except perhaps maybe providing a different perspective on software development.
In summary, the first half of this book (principals of software development) I'd rate as 2 stars, the second half (system design), 4 stars.

This is a great book with balanced perspectiveAug 19, 2010
By Matt
Prior to reading it I struggled with a few things when it came to developing in .Net. For example, I wanted to further develop my object-oriented skills and thought this would be easy to do. Instead, I found out I was having a hard time reconciling using various ADO.Net features like TableAdapters, DataSets and DataTables, with good object-oriented design concepts. The problem was partly that many online references about programming in .NET dealt with using these ADO.Net objects, along with in-line SQL statements, for accessing data. Even the official Microsoft Course I took (Programming with .Net Framework using Microsoft Visual Studio 2005) emphasized these methods.
The tendency to develop in a more procedural style instead of an object oriented one was nearly unavoidable, as exemplified in the examples I found. I even tried for a time to use a layered, object model approach along with DataSets and DataTables and found this to be very clunky to say the least. Now I know why.
The book, Microsoft .NET: Architecting Applications for the Enterprise, recognizes this very situation regarding using these ADO.Net objects on page 154 saying, "Each business component then talks to the DAL either directly or through relatively dumb data objects. The logic is implemented in large chunks of code that can be difficult to understand, maintain, and reuse." It refers to such a design as the Table Module Pattern (TM) and further says on page 165, "TM is based on objects, but it's not an object-based pattern for modeling the business logic. Why? Because it doesn't care much about the business and focuses instead on the tables. TM does have objects, but they are objects representing tables, not objects representing the domain of the problem." Additionally, the book does describes very well how the Table Module Pattern can fit appropriately into a program's architecture, as there are times when using this method is warranted.
It was reading this book that really opened my eyes on how to go about creating a multi-layer application using true object-oriented design in .Net, and getting away from procedural scripting. Primarily I'm referring to using a domain model along with plain class objects for containing business logic and/or data that are not tied to any database design. The book does a great job in helping one understand how and why multi-layered architecture and domain modeling should be used in complex enterprise applications. This is exactly what I was looking for. It touches on other ways to develop the business layer to an application, as well as the other layers, and provides balanced advice for all approaches.
And balance is one thing that stands out in this book. It is not dogmatic at all about how one should construct software. The number one mantra of the book is, "It always depends." With such a refreshing viewpoint, it exposes the reader to a variety of development methodologies and framework. I found this book provides excellent advice on object-oriented design and modern software architecture overall, and specifically on domain-driven design. It also serves as a nice starting point in learning about UML, agile development, unit testing and isolation frameworks, inversion of control frameworks, aspect oriented programming, NHibernate and Entity O/RM frameworks, and the MVC# framework.
