Pro WF: Windows Workflow in .NET 3.0 and Pro WCF: Practical Microsoft SOA Implementation Reviews

These two books are definitely worth getting.

Pro WF: Windows Workflow in .NET 3.0
This is the first book out that shows you how to use the WF tools that are provided by Microsoft in Visual Studio Team System (VSTS) 2005.

The thing I like most about this book is that it is not just a tutorial book, it covers real world scenarios.

Every chapter is very thorough and each chapter builds on the previous chapter. I have listed them below.

Pro WCF: Practical Microsoft SOA Implementation
This book covers everything WCF. I could have done without the SOA introduction, only because I have heard it so many times before. That being said, it is a good introduction to SOA.

The book goes on to cover all the ins and outs of WCF. The book covers the WCF programming model, queue management, reliable messaging, transactions, and security. It covers each topic very thoroughly.

It is written in a very readable format and is definitely worth adding to your library.
