Add-in Express is all-in-one platform for developing any types of Office extensibility projects. You use visual designers instead of error-prone coding to create powerful COM add-ins, smart tags, RTD servers and Excel UDFs for all available Microsoft Office versions, from 2000 to 2010. Using Add-in Express you can create application-level plugins and shared extensions that work on all end-user applications of the Microsoft Office suite, including Outlook, Excel, Word, PowerPoint, Visio, Project, MapPoint, Publisher, Access, FrontPage and InfoPath.

Add-in Express equips you with a strong solution architecture and coherent programming model complemented by a combination of .net components, designers and deployment tools that will free you from a nightmare of tedious coding and ensure a quick and perfect result.

Using Add-in Express visual designers, wizards, modules and components you can create version-neutral, secure, isolated, deployable and automatically updatable Office extensions with your own toolbars, menus, ribbons, form regions, task panes and keyboard shortcuts in minutes.

All available Office versions, from 2000 to 2010 and Office suites, from Student to Enterprise, are supported transparently. Add-in Express .NET is developed in C# and directly supports Visual Basic .NET (VB .NET), C#, and C++ in Visual Studio 2005, 2008 and 2010, as well as Delphi Prism.
