Examining the .Net Class Libraries Using the Object Browser
To be successful in .NET programming requires not only that you know the language you are using (C# in this case) but that you be familiar with the classes in the .NET Framework class library. Navigating the huge number of classes in the class library is a daunting task, and it takes a developer many months to get acquainted with the different classes. This appendix summarizes the features of the various versions of the .NET Framework and explains how to use the Object Browser feature in Visual Studio 2008 to browse the available namespaces and classes in the .NET Framework.
