>Will this book talk about how VFP can work with .NET or is this book about how VFP progammers can more easily migrate to .NET?

Neither actually. The book is about .NET (VS .NET, ADO.NET, ASP.NET, C#, VB .NET, etc.) with a VFP perspective. The book is all about .NET technologies and assumes a VFP developer is reading the book. There isn't much information in the book relative to VFP itself, but there are references to things like the new XMLAdapter class in VFP 8.0 but only briefly. The book is for a VFP developer looking to learn, evaluate, use, etc. .NET, regardless if they are using .NET with VFP or not. I do think that VS .NET adds additional capabilities to VFP development, especially web development such as web forms via ASP.NET and XML web services, etc.

Most VFP developers should feel they can't afford to know what they are missing, so they probably can't afford not to get this book. A good resource on using .NET with VFP is the whitepaper at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfoxgen7/html/usingaspnetwithvfp7.asp, and more resources like this will become available in the future at http://gotdotnet.com/team/vfp.
