Windows Forms is one of the core components of the .NET Framework. It allows developers to create extremely powerful and interactive applications that run on any Windows platform on which the .NET Framework v2.0 has been installed. Windows Forms represents a radical increase in time to market, ease of maintenance, and ease of deployment over other unmanaged development environments such as Visual Basic 6 and unmanaged Visual C++. This is the first of several chapters that will help turn you into an effective Windows Forms developer. This chapter provides an introduction to Windows Forms, how it works, and how you can start creating Windows Forms applications using Visual Studio 2005.
