  • System.Windows.dll (from /Library/Frameworks/Mono.framework/Libraries/mono/4.5/)
Solution

  • System.Configuration is not part (neither as an assembly or namespace) of the BCL shipped with Xamarin.iOS.

    If you get this error it's because you (somehow) got another System.dll (v2.0 from Mono or MS?) into the simulator and this won't work properly.

    Make sure you're referencing only the BCL assemblies from Xamarin.iOS and the problem will go away.
