Add-in Express requirements

With Add-in Express you can build your Office add-ins in VB.NET, C# and Managed C++ (C++/CLI) using Visual Studio 2010, 2012, 2013, 2015 and 2017.

100% backward compatibility

Add-in Express completely supports all Visual Studio versions and editions, so your Office solutions are absolutely identical under different Visual Studio versions. For instance, you can begin your project in Visual Basic 2010 Express and then upgrade it even to Visual Studio 2017 Enterprise and it will still work the same - all you need to do is rebuild your projects.

Express and Community editions of VS fully supported

With Add-in Express you get ready-to-use project templates for all versions of Visual Studio Express 2010 - 2015 and VS Community 2013 - 2017 that enable you to develop all types of Office extensions using C# and VB.NET.

.NET Framework 2.0 and higher

All solution templates as well as the Add-in Express core are compatible with .NET Framework 2.0 and higher.

Microsoft Office 2000 - 2016
