为 nlog 创建配置节处理程序时出错：在 NLog.Targets.DatabaseParameterInfo 上设置 属性 'Layout' 时出错
Error occurred creating the configuration section handler for nlog: Error when setting property 'Layout' on NLog.Targets.DatabaseParameterInfo
我有（我认为是）一个非常简单的 NLog 数据库记录器，没有任何奇特或令人兴奋的东西，但我被大吼大叫，而且我没有任何关于问题所在的信息。
我已将 NLog 连接到 Common.Logging，如下所示：
<common>
<logging>
<factoryAdapter type="Common.Logging.NLog.NLogLoggerFactoryAdapter, Common.Logging.NLog40">
<arg key="configType" value="INLINE" />
</factoryAdapter>
</logging>
</common>
<nlog
internalLogLevel="Trace"
internalLogFile="c:\logs\myservice.api.nlog.log"
throwExceptions="true">

<add assembly="NLog.Extended" />
</extensions>
<targets>
<target
type="Database"
name="database"
dbProvider="mssql"
commandType="Text"
connectionStringName="MyServiceDbConnection"
commandText="INSERT INTO dbo.LOGS (Machine, ExecutingAssembly, UtcTimestamp, Source, Thread, Severity, Username, Message) VALUES (@Machine, @ExecutingAssembly, @UtcTimestamp, @Source, @Thread, @Severity, @Username, @Message);">
<parameter name="@Machine" layout="${machinename}" />
<parameter name="@ExecutingAssembly" layout="${literal:text=MyService.Api}" />
<parameter name="@UtcTimestamp" layout="${date:universalTime=true}" />

<parameter name="@Message" layout="${message} ${exception:format=ToString}" />
</target>
</targets>
<rules>
<logger name="*" minLevel="Debug" writeTo="database" />
</rules>
</nlog>
当我尝试 运行 我的 api 应用程序时，我收到以下错误消息：
Server Error in '/' Application.

这里没有其他错误消息或问题的指示。我做错了什么？
晚了一点可能会有帮助：
如果您使用的是 NLog > 4.0，则 ASP.NET 渲染在 NLog.Web 中。所以你需要用 Nuget 包添加它并引用它如下：
<extensions>
<add assembly="NLog.Web" />
</extensions>
这就是全部，因为您正在使用以下参数：
<parameter name="@Username" layout="${aspnet-user-identity}" />
