asp.net core 3 使用nlog日志组件，使用$ {basedir}保存位置不对，记录下怎么解决

var appBasePath = System.IO.Directory.GetCurrentDirectory();
NLog.GlobalDiagnosticsContext.Set("appbasepath", appBasePath);
var logger = LogManager.LoadConfiguration("nlog.config").GetCurrentClassLogger();

<?xml version="1.0"?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true"
      internalLogLevel="Warn"
      internalLogFile="${gdc:item=appbasepath}\log\internal-nlog.txt">
