Microsoft is committed to promote development with the Outlook 2007 platform. There are new sample templates available: Outlook 2007 Sample: Visual Studio 2005 Templates.
The Outlook 2007 Add-in Templates provide a basic template for developing Outlook 2007 add-ins using Visual Studio 2005. The templates are available in both Visual Basic and Visual C# languages. Each template includes the OutlookItem class, which enables developers to work with generic Outlook items through late-binding, without determining the item type first.
The templates also include wrapper classes that enable you to track multiple Outlook Inspector or Explorer windows. The templates provide an alternative to the Outlook add-in templates available with Microsoft Visual Studio 2005 Tools for the 2007 Office system (VSTO 2005 Second Edition). VSTO 2005 SE is the preferred tool for developing add-ins for Outlook 2007. If you choose to build your add-in by using the Outlook 2007 Add-In Templates, you must add a COM Shim project and a Setup project to your add-in solution.
