Release build is failing with error saying missing implementation on type 'MetroLog.Targets.StreamingFileTarget'

version 1.0.1

Error: NUTC303B:Internal Compiler Error: Method 'instance System.Threading.Tasks.Task`1<MetroLog.LogWriteOperation> MetroLog.Targets.FileTargetBase.DoWriteAsync(System.IO.StreamWriter, System.String, MetroLog.LogEventInfo)' is missing implementation on type 'MetroLog.Targets.StreamingFileTarget' from assembly 'MetroLog.Targets' while loading type 'MetroLog.Targets.StreamingFileTarget'. while computing compilation roots.

in my case, the removal of MetroLog.Target has fixed this error.
left only MetroLog, and this was enough to get the logs
