Microsoft Visual Studio 2005 Tools for the 2007 Microsoft Office System Beta (also known as “Visual Studio 2005 Tools for Office Second Edition Beta” or “VSTO 2005 SE Beta”) is an add-on to Microsoft Visual Studio 2005 that enables you to build application-level add-ins for the 2007 Microsoft Office system as well as the Microsoft Office 2003 Editions.

VSTO 2005 SE Beta features several new important investments in the area of Office programmability. Whether it’s in the revolutionized and highly extensible Office user interface, or in the support for managed add-ins in Office applications not previously covered by Visual Studio 2005 Tools for Office, there exist a number of great new opportunities and challenges for Microsoft Office solution developers. VSTO 2005 SE Beta leverages the solution development environment of Visual Studio 2005 to help you use these opportunities and challenges to take your solutions to the next level.

VSTO 2005 SE Beta also includes support for Microsoft Office InfoPath 2007 forms, previously available as a separate download for Visual Studio 2005. You can design InfoPath 2007 form solutions right in the Visual Studio 2005 environment.
