Jim Cheshire who is working in Microsoft Customer Support wrote a book on the Visual Web Developer 2008 and all the new features that VWD 2008 has for Web designers. Title of the book may be a bit misleading, but if you know that VS 2008 and VWD 2008 provide same HTML and ASP.NET design surface as Expression Web it actually makes sense.

From Jim:

The first thing you’ll notice when you pick up this book is that I use Microsoft Visual Web Developer 2008 Express Edition (available free from Microsoft) to create the ASP.NET application. I chose VWD instead of Expression Web because it’s better suited to building ASP.NET applications. The 2008 version of VWD incorporates many of the features of Expression Web, so users of Expression Web will feel right at home and most of the skills that you learn in this book will translate between both products easily.
