Visual Studio Tools for Office

Visual Studio Tools for Office (VSTO) is the official buzzword for programming Office, including Excel, in .NET. Now, I know what to Google for! Good starting points for programmers (not accountants!) include the MSDN library page for Visual Studio Tools for Office and the book Visual Studio Tools for Office: Using C# with Excel, Word, Outlook, and InfoPath (Microsoft .NET Development Series). This book, co-authored by no less than Eric Lippert, is geared towards professional software developers unlike the plethora of VBA books. Unfortunately, I cannot get the Excel AddIn sample to work as described in the book with Visual Studio 2008 and Excel 2007.
