What distinguishes the web hobbyist from the professional developer is the ability
to store and retrieve data from a server over the Internet. Some readers may have
made that step with PHP or Perl, and for them the journey has already begun. For others,
ASP.NET 3.5 is just the next step in the growth and development of ASP.NET. For them,
much will be familiar and some will be very new. If the transition is from ASP.NET using
Visual Basic to ASP.NET with C#, then you will find even more new, and the transition
to C# is going to be easier than many imagine. Still others are making the first step into
the realm of server-side programming, so just about everything about ASP.NET 3.5 and
C# 3.0 is new.
For those using ASP.NET for the first time, the good news is that the transition to the
server side could hardly be easier. Everything in this book is set up to learn ASP.NET 3.5
and C# 3.0 using Visual Studio 2008. Using the tools built into Visual Studio 2008, you
will quickly learn that most of what needs to be done can be accomplished by dragging
controls into a visual editor. And with the “code behind” method, C# is added in a separate
file, so when editing code, you will see a clear separation—the C# 3.0 code comes
“behind” the ASP.NET 3.5 code. For the most part, though, you need only a minimum
of coding skills in either ASP.NET, which feels a lot like HTML, or C#, which has many
features recognizable from JavaScript. However, make no mistake about it, C# 3.0 is
a full-fledged coding language with the power of any good object-oriented programming
(OOP) language. Most of the C# you need is simply working with functions and subroutines
called by ASP.NET events. As a result, learning C# is quite simple, and you’ll get a lot of
help from Visual Studio 2008 coding tips and built-in IntelliSense. However, if you wish
not to use Visual Studio 2008, all of the code for both the ASP.NET and C# is provided as
well. (You can program it all using Notepad if you like!) You can find a free Express version
of Visual Studio 2008 at www.microsoft.com/express/download/, and it has much of the
functionality of the full-fledged version. Likewise, you will find an Express Edition of SQL
Server 2005, and with them both you can learn ASP.NET 3.5 and C# 3.0 on a budget while
using a powerful development tool.
The main use of ASP.NET in conjunction with C# and Structured Query Language
(SQL) is to store user input in a database and get it back again. If you’ve ever dealt with
forms in HTML, you may know how frustrating it is to build a web site with data entry
that cannot be stored. In fact, without some kind of storage facility and the tools required
to place the data in storage, HTML forms have very limited use. However, not only can
you use plain HTML forms, ASP.NET 3.5 has some web controls that are almost identical
to HTML forms except they have far more functionality. In no time, you’ll be working
with tables and databases to store, fetch, change, and delete a wide variety of data.
In addition to the HTML-like controls, a whole other set of web controls is available to
work with data and create objects that HTML cannot. For example, if your web site needs
a calendar, all you have to do with ASP.NET 3.5 is add a calendar control by dragging it
from the Toolbox and into the editor. Then you can use the Calendar properties to perform
other functions, like reminding you of your upcoming anniversary. (Getting that right can
be worth the price of this book!)
All in all, my hope is that you will enjoy working with ASP.NET 3.5 and C# 3.0 as much
as I have. Not only is it very easy to develop rich interactive web sites using ASP.NET, but
in conjunction with C# 3.0, the toolset is also a very powerful one. With it, you have the best
of all worlds.
