Windows Workflow Foundation is an addition to the WinFx Software Development Kit designed to allow any application to add workflow functionality. Microsoft expects workflow to be one of the next hottest topics within application design and development. This book helps readers who are just beginning their workflow design efforts with WF. All code samples are presented in both VB.NET and C# using Visual Studio 2005. This includes a sample ASP.NET application written in VB.NET that uses workflow and the Windows Workflow Foundation along with a windows application written in C# that uses the same workflow.
I read two books on this topic. The another one is Pro WF. I find this book is easier to understand. Thhis book also includes many real-world samples using WF. The only reason I don't give it 5-stars is because this book contains two languages : C# and VB.NET, that is somewhat confusing for me. I think it's better if Meyers write two editions of this book for each language instead.
