I went to my local bookstore to get a functional understanding of ".NET". My previous readings had been hit and miss and provided little understanding of the new platform.

This book provided that understanding. The writeups on the CLR, assemblies, garbage collection, net components, web services, etc. were skeletal but quite good. I came away with some understanding of what .NET is, why it was developed and why I believe it should leapfrog Java in the web development world.

It wasn't an easy read since it provided good understanding with little detail, and takes some thought; but again, it serves it's purpose well.

As the title says, this book gives the essentials of the .NET framework. It is not an exhaustive treatment, rather, it touches on the main features of .NET. The book assumes that the reader is fluent in object-oriented and component-based programming. Overall, the book was fairly well written with the main features of the .NET framework being clearly explained. The book has no distractive "fluff" in it, so one can easily dive into learning about .NET. The authors give an overview of .NET, and then present a description of the common language runtime (CLR). The common programming model and working with .NET components follow. XML data and web services are clearly explained with a lot of code snippets being given. The book concludes with chapters on ASP, Windows Forms, and mobile devices. The appendices are useful, as sometime acronyms aren't defined in the main text, but are explained in the appendix.

Overall, I found the book well written. The coverage of topics is actually fairly decent. The authors have done a good job of focusing on the essential aspects of .NET. If you're looking for a book that gives gives an overview of the heart of .NET, this is a good book. If you're looking for an exhaustive reference, than you'll probably want something else.

This book delivers exactly what it promises - an excellent overview of essential .NET Framework. Easy to read format, good chapters on IL,Framework,COM+ Interop. Unfortunately very little or no .NET serialization, memory management or threading. But a lot of information for the size of this book. Gives excellent foundation to learn upon.

IMHO, OReilly tends to have the best technology books (I own many) but this book isn't one of them. This book is lightweight even as an introduction. This book is certainly fine for managers, senior architects, and business types, but if you plan to design and write software I recommend Jeff Prosise's "Programming Microsoft .NET" and Jeffrey Richter's "Applied Microsoft .NET Framework Programming", though a bit dated, both cover the .NET framework essentials and then some.

Very well written primer on the .Net framework, internal workings of the CLR and language fundamentals. Great book.
