Mike Murach & Associates has just published VB edition of their ASP.NET 2.0 book - Murach's ASP.NET 2.0 Upgrader's Guide: VB Edition
They have Chapter 3 "Master Pages" up for grabs here - http://www.murach.com/books/ugvb/index.htm - if you are not familiar with the new ASP.NET Master Pages concept be sure to check the sample chapter - cool stuff!
This book assumes you are already familiar with ASP.NET 1.x
On a side note, other than the two books I mentioned before I'm yet to find those that are aimed at VB6 developers moving to VB2005... Do you know any?
