Description Mithosu 2017-08-17 09:13:31 UTC
When I use "Don't Link" in my Debug - iPhone Simulator configuration, Xamarin.Auth is working and also the examples I found on internet. But when I change it to "Link Framework SDKs Only" I get this error:

Mono.Linker.MarkException: Error processing method: 'System.Void Xamarin.Auth.Account::.ctor(System.String,System.Collections.Generic.IDictionary`2<System.String,System.String>)' in assembly: 'Xamarin.Auth.dll' ---> System.ArgumentNullException: Value cannot be null.

Comment 3 Brendan Zagaeski (Xamarin Team, assistant) 2017-08-17 18:54:32 UTC
Thanks for the report.  I'll mark this as a duplicate for tallying purposes.

From that duplicate report, one possible temporary workaround if your application will allow for it is to downgrade the Xamarin.Auth NuGet package to version
