The first sections of this text zero in on what's new and different in VB.NET. From the basics of the language, centering on data types and object-oriented features, this quick-start guide highlights essential language features that every VB.NET programmer needs to know. There's also material here on the underlying .NET framework, from deployment basics (like .NET assemblies) to built-in namespaces. Coverage of delegates and event handling shows how to process events. The substantially different exception handling model of VB.NET is contrasted with the older ways of handling errors.
The heart of this title has to be its reference material (over 400 pages), primarily on the built-in core VB classes in the new .NET version. While there were rumors that VB.NET changed VB completely, this material should reassure you. By providing APIs that resemble older versions, VB programmers still can leverage common string, date, and time and other functions. Every object, method, and property is described, along with sample code, and differences with VB6. A standout here are "gotchas" when using the new APIs compared to VB6. Besides objects and APIs, there is also coverage of language keywords (for logical, looping, and branching statements), too.
The book closes with several useful reference sections, one of which details all the new features to be found in VB.NET. This is almost a must-read for anyone facing the new VB.NET for the first time. Another appendix here lists VB.NET language APIs. While it's true that you can use many languages with .NET, VB.NET Language in a Nutshell covers the APIs that will give VB.NET its real flavor as a new programming language. Both a quick-start guide and a worthwhile reference to use everyday at your desk, this title is a great way to start using VB.NET in real projects quickly. --Richard Dragan
