Hey! Engineer on the App Center team here. We have a detailed explanation of our HockeyApp -> App Center migration plans at https://www.hockeyapp.net/appcenter/transition/ https://www.hockeyapp.net/appcenter/transition/ but the gist is: We won't shut down before all HockeyApp users are happy with what we built and want to switch over. That also includes WPF support. The latest App Center SDK available on NuGet already supports WPF, support for Build and Test are coming in the future!
