NLog在發佈模式下IIS7失敗

Question

編輯：正如Kirk Woll正確指出的那樣，問題是NLog，而不是NInject。因此，讓我改一下這個問題：

EDIT2：現在，我知道這是NLOG +一個IoC的問題，我發現在ASP.NET MVC2 + Ninject + NLog (+ shared hosting?) = NullReferenceException

的解決方案，我有一個使用NInject通過注入的NLogger類項目ILogger接口進入我的所有控制器。史蒂文，回答你的問題，以保持我的web.config清潔，我已經使用NLog.Config文件分開了該配置。

當我在調試模式下的IIS7的目標，代碼工作正常，但在釋放模式下，我得到下面的堆棧跟蹤。

如果任何人有任何想法，爲什麼在調試模式下的代碼將工作，爲什麼在發佈它不會，它將不勝感激。我還在下面列出了我的NLog配置文件。

<?xml version="1.0"?> 
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <target name="file" xsi:type="File" fileName="${basedir}/App_Data//Logs/site.log" 
      layout="${date}: ${message}" /> 
    <target name="eventlog" xsi:type="EventLog" 
      source="Template" 
      log="Application" 
      layout="${date}: ${message} ${stacktrace}" /> 
    </targets> 
    <rules> 
    <logger name="*" minlevel="Info" writeTo="file" /> 
    <logger name="*" minlevel="Fatal" writeTo="eventlog" />   
    </rules> 
</nlog>

Answer 1

好了，我花了排查和解決問題2夜。最初我認爲這個問題與NLog日誌框架有關，所以我轉而使用Log4Net。這很簡單，因爲我使用了Ninject.Extensions.Logging。但是這沒有幫助。

然後我更新到Ninject的預發佈版本，異常消息變得更加清晰：「無法確定DynamicInjectorb709a37f02d44e5a8615c5fde4e0746d的當前類」。

最後一些谷歌上搜索向我指出下面的討論：https://groups.google.com/forum/#!msg/ninject/V_bS0ykJxAA/IBnsGVnL50UJ

Answer 2

我也經歷過類似的「通過創建具有UseReflectionBasedInjection設置爲true的NinjectSettings實例內核嘗試使用反射，而不是」問題。

我的（簡單的）溶液：

通過此線

private static Logger Logger = LogManager.GetCurrentClassLogger(); 

的 「只讀」 關鍵字是可選的替換這些行

private Logger Logger = LogManager.GetCurrentClassLogger(); 

。
