App Center Cloud Build Machines

Important

Visual Studio App Center is scheduled for retirement on March 31, 2025. While you can continue to use Visual Studio App Center until it is fully retired, there are several recommended alternatives that you may consider migrating to.

Learn more about support timelines and alternatives.

Each build runs on a separate, clean virtual machine (VM) no one else has access to. Once the build completes, App Center discards the virtual machine, and all files removed. The artifacts resulting from the build (log files, application files, symbol files) are stored on App Center servers.

Operating System

Builds for iOS and Android apps (including Xamarin and React Native platforms) are run on macOS VMs running the following configuration. (If the specification maps to both VMs, then the newer one is used):

• macOS 11.7 Big Sur
  • iOS (Xcode >= 11.7)
  • Xamarin (Mono >= 6.12.0)
• macOS 12.7 Monterey
  • iOS (Xcode >= 13.1)
  • Xamarin (Mono >= 6.12.0)
• macOS 13.6 Ventura
  • iOS (Xcode >= 14.3)
  • Xamarin (Mono >= 6.12.0)

Builds for UWP apps are run on Hosted Windows Agents using Windows Server 2019 & Visual Studio 2019.
