Introducing .NET Framework 3.0

The .NET Framework is a large collection of libraries that provide support for Visual Basic and the other .NET languages. It includes runtime libraries needed to run the code itself, plus classes for performing common important chores such as working with files, manipulating databases, and displaying controls on forms.

Visual Basic is inextricably tied to the .NET Framework and cannot run without it. Many of the tools that a Visual Basic program uses are actually provided by the .NET Framework. In fact, the two are so closely intertwined that it is often hard to tell which features are part of Visual Basic and which are provided by the Framework.

Recently, Microsoft released version 3.0 of the .NET Framework (formerly known as WinFX). This version of the Framework is clearly linked to the Vista operating system, released at roughly the same time. The Vista operating system uses windows and controls with translucent backgrounds similar to those provided by new controls in .NET Framework 3.0.

Vista is also a visually attractive operating system, clearly showing the work of skilled graphics designers. At the same time, the new Windows Presentation Foundation (WPF) tools in .NET Framework 3.0 are designed for use by graphics designers.

This revision updates the book Visual Basic 2005 Programmer’s Reference for Vista and .NET Framework 3.0. All of the example programs were tested in Vista and minor modifications were made as necessary to allow the programs to continue working in the new environment. The programs’ screen shots were retaken so that you can see the wide-bordered, translucent Aero look and feel of Vista. Completely new chapters and appendixes have also been added to cover key topics added by Windows Vista and version 3.0 of the .NET Framework. These include the following:

• Chapter 14, “UAC Security”

• Chapter 26, “Windows Presentation Foundation”

• Chapter 30, “Windows Workflow Foundation”

• Chapter 31, “Windows Communication Foundation”

• Appendix H, “WPF Controls”

• Appendix I, “Visual Basic Power Packs”
