SLAB SqlDatabaseSink 停止写入 Traces 表

我并行添加了一个 FlatFileSink 以确保侦听器不是问题，它可以很好地写入文件。我还有一个工作正常的 SqlDatabaseSink 单元测试，但是当通过 Global.asax 从主项目订阅时，只有 FlatFileSink 工作。截图如下。

根据@manikrish 的建议添加了 SLAB 内部事件侦听器（非常感谢），这是来自该日志的底层 SQLDatabaseSink 错误“无法加载文件或程序集'Newtonsoft.Json，版本 = 4.5.0.0，文化 = 中性, PublicKeyToken=30ad4fe6b2a6aeed'" - 详情如下，SLAB 内部日志。

接下来，我比较了主项目和单元测试项目（谁的 SQLDatabaseSink 工作）之间的 Newtonsoft.Json 的引用属性，两者都使用版本 6.0.8（我相信 WebApi 5.2.3 附带它），但注意到特定版本在后者。所以，我在主项目中做了同样的改变，仍然没有运气。

此外，主项目的 web.config 和单元测试项目的 app.config 也具有相同的程序集绑定：

  <dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
  </dependentAssembly>

接下来，我尝试通过更改 web.config、packages.config、csproj 中的引用属性来解决绑定重定向问题；基于其他stackoverflow问题（下面的链接）重新安装/更新Newtonsoft.Json以及调用程序集的（Microsoft.Practices.EnterpriseLibrary.SemanticLogging）NuGet包，仍然没有运气- SLAB内部日志中的相同绑定错误，没有证据我的投标重定向。

语义日志记录应用程序块将内部事件记录到称为 SemanticLoggingEventSource 的预定义事件源。您可以创建一个额外的侦听器，将来自此事件源的事件记录到不同的接收器。

例如，下面的代码片段显示了如何将内部事件记录到文件中： 

var slabInternalNotificationsListener = new ObservableEventListener();
slabInternalNotificationsListener.LogToFlatFile(@".\errors.txt");
slabInternalNotificationsListener.EnableEvents(SemanticLoggingEventSource.Log, System.Diagnostics.Tracing.EventLevel.Verbose, Keywords.All);

请查看 SemanticLoggingEventSource 中的日志以了解 SQL 接收器未记录事件的原因。

根本原因是web.config 中的一个程序集周围缺少dependentAssembly 标记：

<dependentAssembly>
    <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
</dependentAssembly>

非常感谢Mani和其他帮助我的SLAB 团队成员，特别是因为根本原因与他们的项目无关。
