VSTO 2005 SE Released
The latest version of VSTO (VSTO 2005 SE) is available for download. You can use VSTO 2005 SE to create add-ins for both Office 2003 and the 2007 Microsoft Office System. VSTO 2005 SE helps you easily customize the new UI features of the 2007 Microsoft Office System, including the ribbon, the custom task pane and Outlook forms region. You do not need to have VSTO installed, in order to use VSTO 2005 SE -- it is an add-in for Visual Studio and you can use it on VSTO 2005 Professional edition.
