CLR 找不到类型，即使它位于同一程序集中

我正在对应用程序中的 WCF 问题进行故障排除，并使用 VS 2010 中的 WCF 服务配置编辑器打开 WCF 跟踪，该编辑器将以下共享监听器添加到 web.config：

    <sharedListeners>
      <add initializeData="D:\Logs\CRCCustomerService\Web_tracelog.svclog"
        type="System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
        name="ServiceModelTraceListener" traceOutputOptions="Timestamp">
        <filter type="" />
      </add>
    </sharedListeners>

现在，当我采取步骤重现错误时，我'我从 System.Diagostics 库抛出一个异常，说它找不到 XmlWriterTraceListener:

Stack Trace: 
System.TypeInitializationException: The type initializer for       'System.ServiceModel.DiagnosticUtility' threw an exception. --->   System.Configuration.ConfigurationErrorsException: Couldn't find type for class System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089. 
at System.Diagnostics.TraceUtils.GetRuntimeObject(String className, Type baseType,    String initializeData) 
at System.Diagnostics.TypedElement.BaseGetRuntimeObject() 
at System.Diagnostics.ListenerElement.GetRuntimeObject() 
at System.Diagnostics.ListenerElement.GetRuntimeObject() 
at System.Diagnostics.ListenerElementsCollection.GetRuntimeObject() 
at System.Diagnostics.TraceSource.Initialize() 
at System.Diagnostics.TraceSource.get_Listeners()

并且它继续了几行，但这建立了上下文。

我的问题是，既然根据 ObjectBrowser 和 Reflector，XmlWriterTraceListener 是与 System.Diagnostics 相同的程序集的成员类，它怎么可能找不到它呢？

其次，由于异常堆栈中的每一行都来自系统代码，我到底如何开始调试这里的根本原因？

原文

I'm troubleshooting a WCF problem in our application, and turned on WCF tracing with the WCF Service Configuration Editor in VS 2010, which added the following sharedListener to the web.config:

    <sharedListeners>
      <add initializeData="D:\Logs\CRCCustomerService\Web_tracelog.svclog"
        type="System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
        name="ServiceModelTraceListener" traceOutputOptions="Timestamp">
        <filter type="" />
      </add>
    </sharedListeners>

Now, when I take steps to reproduce my error, I'm getting an exception thrown from the System.Diagostics library saying that it can't find XmlWriterTraceListener:

Stack Trace: 
System.TypeInitializationException: The type initializer for       'System.ServiceModel.DiagnosticUtility' threw an exception. --->   System.Configuration.ConfigurationErrorsException: Couldn't find type for class System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089. 
at System.Diagnostics.TraceUtils.GetRuntimeObject(String className, Type baseType,    String initializeData) 
at System.Diagnostics.TypedElement.BaseGetRuntimeObject() 
at System.Diagnostics.ListenerElement.GetRuntimeObject() 
at System.Diagnostics.ListenerElement.GetRuntimeObject() 
at System.Diagnostics.ListenerElementsCollection.GetRuntimeObject() 
at System.Diagnostics.TraceSource.Initialize() 
at System.Diagnostics.TraceSource.get_Listeners()

And it goes on for several more lines, but this establishes the context.

My question is, since, according to ObjectBrowser and Reflector, XmlWriterTraceListener is a member class of the same assembly that System.Diagnostics is, how can it NOT not be able to find it?

And secondly, since every single line in the exception stack comes from system code, how on earth do I begin to debug the root cause here?
