This is expected you are running version 5.2 on 5.0 without using stable API. Use msbuild to build your project or pass -sdk to mcs

Should I open a new bug report? Still happening in Xamarin.iOS
Comment 4 Andy 2017-06-02 20:54:56 UTC
Actually, I think I found the culprit. The latest version requires an alpha update in Xamarin to Mono.
Comment 5 mikerkirk 2017-07-20 06:08:40 UTC
It's still happening, so what's the workaround? When will it be fixed?
Comment 6 Marek Safar 2017-07-27 12:25:44 UTC
What is still happening, same stack trace? What version are you on?
