Visual Studio App Center can automatically publish builds to a Store connection like TestFlight or Google Play Store. When working on a new feature, ensuring that the latest build is available to stakeholders and testers can be cumbersome. Instead of doing it manually, if you setup your feature branch in App Center Build to publish successful builds, stakeholders will always be up-to-date on the latest release.
Start by setting up a store connection, then navigate to branch settings in Build. In the Distribution section, choose the appropriate destination for your app.
