Walkthrough: Building an Add-in using Visual Studio

If you’re just getting started and want to use Visual Studio, I highly recommend watching a walkthrough tutorial that I recorded in late 2015: https://channel9.msdn.com/series/officejs/End-to-End-Walkthrough-of-Excel-JavaScript-Add-in-Development.

In the video, I walk through the end-to-end process of building an Office Add-in for Excel: from launching Visual Studio, to writing a bit of JavaScript code that uses the new Excel 2016 APIs, to adding some basic UI tweaks, to talking through the publishing options, debugging, and more.

The video touches on some API topics that are covered in much greater detail in this book – but it also shows the process of creating a project and debugging using Visual Studio, which is crucial for getting started. If you’ve not built an Office Add-in before, I highly recommend the video.

For those looking for written instruction, just on the Visual Studio piece: there is also official documentation for creating a project on https://dev.office.com/docs/add-ins/get-started/create-and-debug-office-add-ins-in-visual-studio.
