Verbose build output

We're attempting to do a release build of a Xamarin iOS app. When using 'Link Framework SDKs Only' for the Release configuration and we get an error:

/Projects/Fluker Post/Xplat/iOS/MTOUCH: Error MT2101: Can't resolve the reference 'System.Void Amazon.CloudWatchLogs.AmazonCloudWatchLogsClient::.ctor(Amazon.RegionEndpoint)', referenced from the method 'Serilog.LoggerConfiguration Serilog.Sinks.AwsCloudWatch.AwsCloudWatchConfigurationExtension::AmazonCloudWatch(Serilog.Configuration.LoggerSinkConfiguration,System.String,System.String,System.String,Serilog.Sinks.AwsCloudWatch.ILogEventRenderer,Serilog.Events.LogEventLevel,System.Int32,System.Nullable`1<System.TimeSpan>,System.Boolean)' in 'AWSSDK.CloudWatchLogs, Version=3.3.0.0, Culture=neutral, PublicKeyToken=885c28607f98e604'. (MT2101) (iOS)

So following your hints at https://developer.xamarin.com/guides/ios/troubleshooting/mtouch-errors/#MT2101, I'm submitting a bug report with full verbosity enabled.

Just for context, the we're using the popular Serilog package to handle logging in our app. This allows logs to be submitted to AWS' CloudWatchLogs service. You'll see that I tried to exclude the AWSSDK.CloudWatchLogs assembly from the linking process too in my mtouch arguments, but this didn't seem to help.

The build output is included as an attachment. The DLL that's causing this issue comes from the AWSSDK.CloudWatchLogs nuget package (version 3.3.4.3).

Hello,

I'm not familiar with the package in question. Could you please provide a small test application that shows the usage of the package and that reproduces the issue? A small single window iOS application that uses the method you mention would be enough. 

I would also appreciate if you could provide you full build env information which you can find in the About Visual Studio dialog. That way we can pin point the exact environment in order to reproduce the issue.

Thanks!
