log4net AdoNetAppender的记录延迟了吗？

Question

我有这样一个AdoNetAppender设置：

  <log4net>
    <appender name="AdoNetAppender_SqlServer" type="log4net.Appender.AdoNetAppender">
      <connectionStringName value="DefaultConnection" />
      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
      <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message]) VALUES (@log_date, @thread, @log_level, @logger, @message)" />
      <useTransactions value="false" />
      <parameter>
        <parameterName value="@log_date" />
        <dbType value="DateTime" />
        <layout type="log4net.Layout.PatternLayout" value="%date{yyyy'-'MM'-'dd HH':'mm':'ss'.'fff}" />
      </parameter>
      <parameter>
        <parameterName value="@thread" />
        <dbType value="String" />
        <size value="255" />
        <layout type="log4net.Layout.PatternLayout" value="%thread" />
      </parameter>
      <parameter>
        <parameterName value="@log_level" />
        <dbType value="String" />
        <size value="50" />
        <layout type="log4net.Layout.PatternLayout" value="%level" />
      </parameter>
      <parameter>
        <parameterName value="@logger" />
        <dbType value="String" />
        <size value="255" />
        <layout type="log4net.Layout.PatternLayout" value="%logger" />
      </parameter>
      <parameter>
        <parameterName value="@message" />
        <dbType value="String" />
        <size value="4000" />
        <layout type="log4net.Layout.PatternLayout" value="%message" />
      </parameter>
    </appender>

    <root>
      <level value="DEBUG" />
      <appender-ref ref="AdoNetAppender_SqlServer" />
    </root>
  </log4net>

从技术上讲，它是有效的，因为当我停止运行在IIS 8 Express上的网站时，记录就会显示出来。，这正是问题所在，除非我停止网站，否则记录就不会出现。

我试过和useTransactions断断续续的联系。

有人能帮忙吗？

尝试将缓冲区大小设置为1：

 <appender name="AdoNetAppender_SqlServer" type="log4net.Appender.AdoNetAppender">
      <connectionStringName value="DefaultConnection" />
      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
      <commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message]) VALUES (@log_date, @thread, @log_level, @logger, @message)" />
      <useTransactions value="false" />
      <bufferSize value="1" />
