Add-in Express for Office and .NET

What is Add-in Express for Office and .NET?

Add-in Express for Office and .NET is the complete framework for developing Microsoft Office business extensions, such as Office COM Add-in, Outlook plug-in, Excel XLL, UDF, RTD Server, and smart label.

It works with all editions of Visual Studio, including Express and all versions of Microsoft Office from 2000 to Office 2019.

Create world-class Office extensions

Add-in Express for Office and .NET offers a variety of visual designers, components, item templates and Visual Studio projects, and deployment tools that make creating Microsoft Office quality extensions easy and fun.

You no longer have to worry about implementing extensibility COM interfaces or manually coding the Office add-in UI using XML. Add-in Express makes deploying your applications a one-click operation and removes the headache of the entire process of manually creating these implementations and the work of having to receive the Windows registry.

A project for all versions and applications of Office

Add-in Express has a neutral version-optimized core that is written in C# and is based on the .NET framework, with low-level COM and Windows API interoperability. This makes it easy to create a Visual Studio project that supports all versions and editions of Microsoft Office and multiple applications in the Office suite (Outlook, Word, Excel, Powerpoint, and more).

100% version-to-version compatibility

You are not limited in your choice of Visual Studio versions or development editions with Add-in Express. As an example, you can use Visual Studio 2010 Standar to create an add-in for Office 2000 or 2019.
