Advice on Buying book for Enterprise Library - January 2006 release

[bytebugs]

Hello Folks,

Can anyone suggest me a good book to learn using the Microsoft
Enterprise Library Application Blocks.

I can only find two books on the net
1. The Definitive Guide to the Microsoft Enterprise Library by Keenan
Newton.
This book has yet not released
2. Effective Use of Microsoft Enterprise Library : Building Blocks for
Creating Enterprise Applications and Services (Microsoft .Net
Development Series) (Paperback)
by Len Fenster

I am feeling hesitant for buying the book by len fenster as it is based
on the July 2005 release.
Since then the Configuration Application Block, Data Access Block and
Logging Application Block have been changed drastically. So I dont know
if it will be a good idea to buy this book or not as I it would not
feature the changes.

Thanks in advance

Regards,
Bugs.

I recently purchased the only available book you mentioned. It is of some
value. Many of the concepts are still valid. I found the documentation from
the Patterns group almost impossible to come up with good understanding of
what was being done this book helped even while working with the 2006
version.
