If you find yourself working with Windows Workflow Foundation 4.0 and you have basic knowledge of C#/.NET Framework/VB and workflow, this book is for you. It will be best if you know both C# and VB, because WF 4.0 expressions can be written only in VB (at the time of writing). With this book, you will be able to enhance your applications with flexible workflow capabilities using WF 4.0. To follow the recipes, you will need to be comfortable with .NET Framework, C# programming, and the basics of SOA and how to develop them.
