Known Issues

  • [Mono Framework] – 45761 – After network reconnected, web request fails for a couple of minutes with a NameResolutionFailure
  • [Xamarin for Visual Studio], [Xamarin Studio]43566 – In a few remaining scenarios, the iOS Designer initialization process might still cause a running iOS 10 simulator to become non-responsive. The designer initialization happens when opening an iOS project in Xamarin Studio and during the connection to the remote Mac in Visual Studio. This issue does not affect Xcode 7.3, iOS 9.3 (and lower) simulators.
    • Workaround: Quit and restart the simulator after the designer has initialized. You can then proceed to use the simulator again as normal.
