Introducing C#
Welcome to the first chapter of the first section of this book. Over the course of this section, you
look at the basic knowledge required to get up and running with C#. In this first chapter, you get
an overview of C# and the .NET Framework, and you consider what these technologies are, the
motivation for using them, and how they relate to each other.
You start with a general discussion of the .NET Framework. This is still a new technology and con-
tains many concepts that are tricky to come to grips with at first (mainly because the Framework
introduces a new way of doing things to application development). This means that the discussion
will, by necessity, cover many new concepts in a short space of time. However, a quick look at the
basics is essential to understand how to program in C#, so this is a necessary evil. Later in the
book you will revisit many of the topics covered here in more detail.
After this general discussion, you move on to a simple description of C# itself, including its origins
and similarities to C++. Finally, you look at the primary tool used throughout this book: Visual
Studio 2005 (VS).
In this chapter, you learn:
What C# and the .NET Framework are
How the .NET Framework works and what makes it special
What you can do with C#
What Visual Studio 2005 is and how it fits in with this book
What Is the .NET Framework?
The .NET Framework is a new and revolutionary platform created by Microsoft for developing
applications.
