What is this library?

Excel-DNA eases the development of Excel add-ins using .NET. Add-ins created with Excel-DNA can export high-performance user-defined functions and macros, and can be packed into a single file for easy distribution and installation. Excel versions 97 through 2016 can be targeted with a single add-in. Advanced Excel features are supported, including multi-threaded recalculation (Excel 2007 and later), registration-free RTD servers (Excel 2002 and later) and customized Ribbon and Task Pane interfaces (Excel 2007 and later) and asynchronous functions (Excel 2002 and later). Excel-DNA supports the .NET runtime version 2.0 (which is used by .NET versions 2.0, 3.0 and 3.5) and version 4.0 (the version number used by .NET 4, 4.5 and 4.6). The Excel-Dna Runtime is free for all use, and distributed under a permissive open-source license that also allows commercial use.
