Log4Net not writing to the database

Question

I've checked the connection string (I got it from the server explorer).

I've checked the commandText in log4net config.

I've checked the database permissions (integrated security is fine and works outside of the log4net class).

I've checked the repository's configured property (it is configured, it finds the config file fine).

I've also checked that the fields defined in the config file match the attributes (field size etc.) of the table in the database.

Any ideas?

When I'm debugging it seems to be hitting all the right methods at all the right times, with no exceptions raised.

    <param name="AppendToFile" value="true"/>
    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%d [%t] %-2p %c [%x] - %m%n"/>
    </layout>
  </appender>

  <root>
    <appender-ref ref="ADONetAppender"/>
    <appender-ref ref="FileAppender"/>
  </root>

</log4net>

It's writing to neither appender.

I would recommend turning on Log4Net debugging:

<add key="log4net.Internal.Debug" value="true"/>

That may point you in the right direction if there's an error that's occurring behind the scenes. The output will be directed to the console output in the IDE or in the command line.
