This book is designed to cover three areas. The first section teaches the basic concepts of mobile development, and walks the reader through the basics of WAP, WML, and the concepts of devices with limitations in size, memory, screen, bandwidth, etc. The core section of the book goes on to teach ASP.NET developers how to create mobile controls to produce targeted output suitable for viewing on one of these devices. The next section then applies this to Visual Studio .NET, with chapters showing how to do this from within the Studio environment. The book finishes with a case study, collecting the concepts discussed throughout the book into a worked example. This book teaches the ASP.NET programmer all of the necessary concepts they need to understand to be able to competently create applications using these controls.
