Visual Studio Tools for Office (VSTO) was released in August of 2003. It brought the power of .NET to developing Word and Excel applications. While powerful, it was also lacking in some key features, and difficult to use. VSTO 2005 will be released as part of the Whidbey release. It will be incorporated in the more advanced versions of Visual Studio .NET 2005, and will also be available as a stand-alone product. It has corrected many of the major problems with the first version, and is poised to experience a rapid growth in usage. Coverage has been expanded to include Outlook and InfoPath in addition to Word and Excel. This book is not only written by key members of the team that developed VSTO 2005, but it will also be the first book available on VSTO. The authors provide both an introduction to VSTO as well as a tutorial for using it, including lots of practical examples, and a refreshing honesty about both the strengths and pitfalls of the technology. This book will be a must-have for all the developers considering VSTO.
