Write a Custom Outlook Add-In with Visual Studio Tools for Office

(Laurence Moroney) Visual Studio Tools for Office (VSTO) is an add-on to Visual Studio 2005 that gives developers much more direct IDE support and easier access to the rich programming model provided by the Microsoft Office platform than did previous versions of Visual Studio. VSTO simplifies building applications that use Office's functionality and building add-ins to existing Office applications, such as Outlook or Excel. The ubiquity of the Office platform offers swathes of powerful functionality already on your users' desktops; so you can take advantage of it by reusing the components.
