With COM and .NET Component Services, skilled COM developers can leverage their knowledge for the next generation of components to be built for Microsoft's new .NET framework. A primary goal of Microsoft's COM+ is to provide proven design solutions for scalable systems. Assuming experience with classic COM, COM and .NET Component Services focuses on the added services of COM+, including support for transactions, queued components, events, concurrency management, and security. Along the way, it ably demonstrates that COM+ is a masterpiece of design and usability from the ground up--truly a mature set of component services oriented for the middle tier. COM+ provides a foundation for robust, enterprise-wide, mission-critical distributed applications. And it's not limited to Internet applications. You can use COM+ services in the same places as classic COM components: in-house two-tier information systems, client-tier controls, desktop applications, machine control components, and every other conceivable application of COM. COM and .NET Component Services is the first book to stress the importance of learning to use COM+ services for both .NET and COM component-based applications. Since most companies have considerable investment in existing code base and development skills, COM+ can serve as a migration path for companies and developers. Companies can start (or continue) their projects in COM, using COM+ as a supporting platform for component services, and then when the time comes to move to .NET, they can start plugging .NET components seamlessly into the same architecture, reusing and interacting with their existing COM components.

Amazing explanations of COM+ Services - 2001-12-07
Reviewer Rating:
I have read several books now on COM+ and MTS before it, and I have never quite understood how everything ties together and works together. So I have been stumbling in the dark on this for years. My components work, but I never knew if they worked optimally.

This book changed all that. Finally, it all makes sense. This is by far the best book on this subject that I have read. Every piece of COM+ is explained clearly and with enough detail to get the point across without bogging down the reader. It even answered some difficult mysteries for me such as "Why is the JITA checkbox greyed out for my transactional components?" I couldn't even find an answer for that one on the newsgroups.

The .NET coverage is brief and was probably an afterthought (in that it appears in a chapter at the end rather than integrated throughout the book), but it is enough to get started. I am looking forward to a second edition of this book that focuses on .NET and has all the code examples in C#. Juval, please write that!

Beware...COM Services and some pages about .NET - 2003-07-31
Reviewer Rating:
Don't get me wrong!! It's a great book, for understanding COM+ and use it, without all the headache of learning "why".
But i think many people would believe is a good about .NET and how to use COM Services, but you will get only a few pages about implementing both technologies together.
But, like i've said, it's a good book about COM Services.

Know COM, Learn COM+ and .NET component Services - 2001-12-01
Reviewer Rating:
This is one of the best technical books, I have read. It assumes knowledge of COM and object-oriented technologies. The clarity in the areas COM+ interception, threading, security, transaction handling is exceptional.

Excellent, straight to the point - 2003-11-22

Don't worry about the slight .Net presence in the book; there is no "new generation" of COM+ in .Net, .Net simply includes COM+ (of course there is a new name for it: Enterprise Services, but this is just pure marketing matter)!
I haven't finished the book yet, but I can say Juval found the right way in explaining most of the COM+ features and why are they indispensable in building enterprise apps by focusing on the business logic and not on the plumbing (object pooling for supporting scalability, transaction management, synchronization etc). The writing style is clear, the content is exhaustive enough for covering all the aspects of COM+/.Net Enterprise Services and, the last but not the least, the book has less than 400 pages.
Other recommended books about COM+:
-Transactional COM+, by Tim Ewald: if you need to know more COM+ internals about contexts, apartments etc.
-Programming Distributed Apps with COM+ and VB6, by Ted Pattison: excellent lecture, easy and explains very well the "why"s.
- Visual Basic and COM+ Programming: by Peishu Li. Very similar style with Juval's book, except that the code is VB instead of C++.

Very Good Condition(Just like New) - 2003-01-31

The book was in excellent condition and looks like new. Although the shipping was 2 days late but based on the book condition its worth waiting.
I can rate A++.
