Question

我将新的（NuGet）组件 Microsoft.AspNet.WebApi.OwinSelfHost 添加到现有的有效多线程应用程序中，该应用程序大量使用 System.Data.SQLite 的EntityFramework

现在完全不可预测的任何查询随机都可以通过callstack失败，这显示添加的 Owin 组件以某种方式集成到.NET的内部日志系统中（我个人既不理解也不使用（我使用） NLog 代替））使用Microsoft.Owin.Hosting.Tracing.DualWriter：

System.Data.Entity.Core.EntityCommandExecutionException occurred
  HResult=-2146232004
  Message=An error occurred while executing the command definition. See the inner exception for details.
  Source=EntityFramework

       InnerException:

我已经尝试禁用SQLite端的日志记录：

System.Data.SQLite.SQLiteLog.Enabled = false;

和Owin：

appBuilder.Properties.Remove("host.TraceOutput");
appBuilder.Properties.Remove("host.TraceSource");
appBuilder.Properties.Remove("server.LoggerFactory");

但没有成功/改变。

TraceListener处理完全不相关的组件之间的错误
