NLog没有从引用的dll中写入

我创建了一个用于发送电子邮件的dll。我有NLog包含在该项目中，记录到c:'logs{logfilename.log} <——这是一个错误或事件日志。当在本地使用项目时，它工作得很好，并在测试期间写入文件。当我从另一个也有NLog的项目引用电子邮件dll时，它不会输出到日志文件。电子邮件dll中的配置位于引用它的新项目的bin目录中。我可以使用跟踪从新项目创建日志，但它没有打印电子邮件dll条目。有什么特别的我需要在我的新项目做得到电子邮件dll写日志?我已经搜索了这个问题的答案，但关键字没有产生我需要的结果。我刚接触NLog，请温柔点。

NLog.config

这是我的Log.cs从编译的实用程序dll

using NLog;
namespace NTC.Utility
{
    internal static class Log
    {
        public static Logger Instance { get; private set;}
        static Log()
        {
            LogManager.ReconfigExistingLoggers();
            Instance = LogManager.GetCurrentClassLogger();
        }
    }
}

这一行在邮件发送后调用我的Logging Method。

LogEmailSent(imperEmail);

调用这个方法…

    private void LogEmailSent(EmailMessage email)
    {            
        Logger logger = LogManager.GetCurrentClassLogger();
        LogEventInfo thisEvent = new LogEventInfo(LogLevel.Info, "default","Email Sent");
        thisEvent.Properties["From"] = email.From;
        thisEvent.Properties["To"] = EmailCollectionToCsv(email.ToRecipients);            
        thisEvent.Properties["Bcc"] = EmailCollectionToCsv(email.BccRecipients);
        thisEvent.Properties["CC"] = EmailCollectionToCsv(email.CcRecipients);
        thisEvent.Properties["Subject"] = email.Subject;
        thisEvent.Properties["Body"] = email.Body;
        thisEvent.Properties["Attachments"] = AttachmentCollectionToCsv(email.Attachments);
        logger.Log(thisEvent);
    }
