24–26 May 2022, hybrid (mostly online). A soft return to in-person — invite-only physical presence in Seattle, free digital stream for everyone else. The first Build after the pandemic but not really the first one back.
What we took away
- .NET MAUI 1.0 GA. Single-codebase cross-platform UI for Android, iOS, macOS, and Windows — the official successor to Xamarin.Forms. This shipped on Day 1 of the conference and changed how we plan customer mobile projects from that morning forward.
- Azure Container Apps GA. Serverless containers for microservices, with no Kubernetes ceremony to learn first.
- Microsoft Intelligent Data Platform. Azure SQL, Cosmos DB, Synapse, Purview, and Power BI re-framed as a single data fabric — the story that would become Microsoft Fabric one year later.
- Cosmos DB updates: serverless up to 1 TB, hierarchical partition keys, free 30-day trial, Linux desktop emulator.
- Microsoft Dev Box preview — cloud-hosted, pre-configured developer workstations on Azure.
- GitHub Copilot announced for June 21, 2022 general availability — preview-to-paid in roughly a month.
Why it mattered for us
.NET MAUI hitting GA was the moment our internal "should we build native or hybrid?" conversation collapsed for years. By summer we were prototyping the Kühne+Nagel CST mobile app on MAUI — a single codebase running on iOS and Android phones in the field. That project shipped in 2023 and is still live on both stores.
"Over 5 million .NET developers now have a first-class, cross-platform UI stack." — the .NET MAUI GA blog post
We're one of those five million, and at Build 2022 it stopped being a promise.
