关于c＃：不要将日志写入数据库NLog + ASP .NET 5 + SQL Server

Do not write logs to the database NLog + ASP .NET 5 + SQL Server

我的应用程序基于ASP .NET 5构建
我曾经在.NET Core上做过一个项目，一切都很好，日志没有问题。但是在ASP.NET 5中，我不知道如何执行此操作
我正在尝试使用此配置将日志写入数据库：

https://github.com/nlog/NLog/wiki/Database-target#example-configurations

这是我的配置文件：

我在数据库中创建了表

我尝试对日志进行测试调用，但未写下任何内容：

1

public string Index()
{
Logger log = LogManager.GetCurrentClassLogger();
log.Trace("trace message" );
log.Debug("debug message" );
log.Info("info message" );
log.Warn("warn message" );
log.Error("error message" );
log.Fatal("fatal message" );

return"start...";
}

但是数据库中没有记录
