NLOG与.net核心1.0 - LayoutRenderer无法找到

这是非常相关的this question，但对于.NET的核心。我有一个用户ID添加自定义布局渲染器和它的工作，直到我在project.json为“netcoreapp1.0”试图从“net461”升级。当我这样做，我不得不删除NLog.Extensions，因为它给了我这个错误：NLOG与.net核心1.0 - LayoutRenderer无法找到

Package NLog.Extensions 1.0.1 is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0). Package NLog.Extensions 1.0.1 supports: net45 (.NETFramework,Version=v4.5)

一切编译罚款，但在运行时，我得到的内部nlog.txt日志文件中这个错误，并当然，它不会打我的自定义布局渲染：

NLog.NLogConfigurationException: Error when setting property 'Layout' on NLog.Targets.DatabaseParameterInfo ---> System.ArgumentException: LayoutRenderer cannot be found: 'aspnet-user-id'

是否有NLog.Extensions的替代品，还是我失去了一些东西？

下面是引用自project.json：

"NLog.Extensions.Logging": "1.0.0-rtm-alpha4", 
"NLog.Web.AspNetCore": "4.2.4" },

我把一切都在Startup.cs和NLog.config完全相同的配置，因为它是不断变化的框架之前的版本。如果发布这些内容很有帮助，请告诉我，我会这样做。我很感激帮助。

编辑：新增project.json内容

哪个构架目标定制NLOG分机图书馆吗？（project.json） – Julian

嗨@Julian。我希望你会看到这个问题。我想如果有人知道答案，你会的。我添加了相关的project.json部分。谢谢！ –

假设你我们正在使用this NLog.Extensions package - 它不支持NETSTANDARD，所以你不能用netcoreapp1.0

升级为使用它ASP.NET（到ASP.NET Core）不是微不足道的，看起来库不再活跃。

幸运的是在NLog.Web.AspNetCore一个aspnet-user-identity，你都已经包括在内。

因此，与${aspnet-user-identity}

第三次尝试...：O – Julian

谢谢。自定义LayoutRenderer实际上是让过去的$ {ASPNET用户身份}（这是一个电子邮件地址），因为我们需要记录用户的ID而不是，因为电子邮件地址会随时间改变。我想我必须找出另一种方式来存储用户ID。 –

如果这还不是你要找的，请随时在GitHub上创建一个问题：https：//github.com/NLog/NLog – Julian

更换${aspnet-user-id}我不知道为什么，但是当我注释掉的电子邮件目标和记录器，自定义LayoutRenderer又开始工作。仅供参考，以下是当前的nlog.config文件，其中注释了电子邮件内容。

    </connectionString> 

    <commandText>

    <parameter name="@level" layout="${level}" /> 
    <parameter name="@message" layout="${message}" /> 
    <parameter name="@user" layout="${aspnet-user-id} " /> <!-- This is a custom attribute, set in NLogHelper.cs--> 
    <parameter name="@exception" layout="${exception:tostring}" /> 
</target> 

<!--<target name="email" xsi:type="Mail"

</rules> 
<extensions> 
    <!--enable NLog.Web for ASP.NET Core--> 
    <add assembly="NLog.Web.AspNetCore"/> 
</extensions> 
</nlog>

如果我取消了电子邮件的一部分，我得到下面的错误，不说对电子邮件部分是一个问题什么。我甚至没有尝试过的电子邮件部分的唯一原因是因为我意识到，我用来获取电子邮件时，异常发生，现在我不这样做，并试图解决这个问题。

这是因为NLog for .NET Core不支持电子邮件目标，因为微软没有移植system.mail。请检查https://github.com/NLog/NLog/wiki/platform-support – Julian

谢谢@Julian。您对NLog的帮助和工作无疑是值得赞赏的。 –

在根据节点添加您的NLog.config文件下列

<add assembly="NLog.Web.AspNetCore" />

希望这回答了你的quesetion。
