Microsoft Build

Come together at Microsoft Build May 24–26 2022, to explore the latest innovations in code and application development—and to gain insights from peers and experts from around the world.

Unlike Google and Apple, Microsoft Build is usually committed to being a developer-heavy event. That means more on-stage coding and developer sessions and fewer Surface announcements. You can, however, expect to hear new info centered around how developers can create experiences for Windows and the other Microsoft 365 services like Microsoft Teams.
