Could you share the complete build output and Exception stack trace? It will help us to troubleshoot the issue

Same for me.
How I can get the complete build output and Stack Trace? Sorry, I'm a Xamarin newbie.

[prashantvc]

@lantonello you can find the instructions here https://developer.xamarin.com/guides/cross-platform/troubleshooting/questions/version-logs/#debug-logs-for-xamarin-apps

This should be resolved via dotnet/android#1142 which will be included in a future build.

Is there a workaround @JonDouglas I haven't seen this at all. Do people just need to do a clean/rebuild?

@jamesmontemagno https://bugzilla.xamarin.com/show_bug.cgi?id=61073#c40 has a workarond, ensure to "unblock" the dll after downloading via properties!
