Building add-ins with commands

Because of their advantages, we’re encouraging all developers building add-ins to use commands. In fact, soon we’ll start requiring add-ins submitted to the Office Store to use them for scenarios where it makes sense. In this post, I wanted to share the easiest way to get started building an add-in with commands.

Introducing add-in commands

Back at Build and Ignite, we announced a brand new feature, that we’re very excited about – Outlook add-ins (formerly called apps for Outlook) can now place buttons on the ribbon in Outlook! This simultaneously simplifies interacting with add-ins, as well as makes their presence more visible and engaging. In a two-part series, we wanted to share our thinking behind why we invested in commands and how they work, as well as walk through a sample add-in with a command. This is the first post in the series.
