无法在配置源中找到"日志记录"的配置部分

Question

我得到以下异常.我正在使用Enterprise Library 6.0 Application Logging Block.

    System.InvalidOperationException was unhandled by user code
  HResult=-2146233079
  Message=The configuration section for Logging cannot be found in the configuration source.
  Source=Microsoft.Practices.EnterpriseLibrary.Logging
  StackTrace:
       at Microsoft.Practices.EnterpriseLibrary.Logging.LogWriterFactory.LogWriterConfigurationBuilder.Create()
       at Microsoft.Practices.EnterpriseLibrary.Logging.LogWriterFactory.Create()
       at Logger..ctor() in \MBSLogger.cs:line 19
       at EventLoggingTest.test_log_simple_exception() in c:\Users\Vinay.Joseph\Documents\Visual Studio 2013\EventLoggingTest.cs:line 20
  InnerException: 

代码库如下.

       IConfigurationSource configurationSource = ConfigurationSourceFactory.Create();
        LogWriterFactory logWriterFactory = new LogWriterFactory(configurationSource);
        Logger.SetLogWriter(logWriterFactory.Create());


        if (!Logger.IsLoggingEnabled())
        {

        }
        else { 
            Logger.Write(new LogEntry(){
                Severity = System.Diagnostics.TraceEventType.Information,
                TimeStamp = DateTime.Now,
                Message = "Hello World"
            });
        }

请告诉我哪里出错了.

app/web.config是什么样的？你有日志配置设置吗？
