Preface
Web development is very exciting. There’s nothing like the feeling you have after
you place your first dynamic web site online, and see your little toy in action while
other people are actually using it!
Web development with ASP.NET is particularly exciting. If you’ve never created a
dynamic web site before, I’m sure you’ll fall in love with this area of web development. If you’ve worked with other server-side technologies, I expect you’ll be a little shocked by the differences.
ASP.NET really is a unique technology, and it provides new and extremely efficient
ways to create web applications using the programming language with which you
feel most comfortable. Though it can take some time to learn, ASP.NET is simple
to use. Whether you want to create simple web forms, feature-rich shopping carts,
or even complex enterprise applications, ASP.NET can help you do it. All the tools
you’ll need to get up and running are immediately available and easy to install, and
require very little initial configuration.
This book will be your gentle introduction to the wonderful world of ASP.NET,
teaching you the foundations step by step. First, you’ll learn the theory; then, you’ll
put it into practice as we work through practical exercises together. To demonstrate
some of the more complex functionality, and to put the theory into a cohesive,
realistic context, we’ll develop a project through the course of this book. The project—an intranet site for a company named Dorknozzle—will allow us to see the many components of .NET in action, and to understand through practice exactly
how .NET works in the real world.
We hope you’ll find reading this book an enjoyable experience that will significantly
help you with your future web development projects!
Who Should Read This Book?
This book is aimed at beginner, intermediate, and advanced web designers looking
to make the leap into server-side programming with ASP.NET. We expect that you’ll
already feel comfortable with HTML and a little CSS, as very little explanation of
these topics is provided here.

By the end of this book, you should be able to successfully download and install
Visual Web Developer 2008 Express Edition, and use it to create basic ASP.NET
pages. You’ll also learn how to install and run Microsoft SQL Server 2005 Express
Edition, create database tables, and work with advanced, dynamic ASP.NET pages
that query, insert, update, and delete information within a database.
All examples provided in the book are written in both Visual Basic and C#, the two
most popular languages for creating ASP.NET web sites. The examples start at beginners’ level and proceed to more advanced levels. As such, no prior knowledge of either language is required in order to read, understand, learn from, and apply
the knowledge provided in this book. Experience with other programming or
scripting languages (such as JavaScript) will certainly grease the wheels, though,
and should enable you to grasp fundamental programming concepts more quickly.
