Another log4net, fluent nhibernate configuration issue

This is driving me crazy... I've spent half a day trying to turn everything aroung but I can't get log4net to spit out anything about NHibernate.

Here's my current Fluent NHibernate config:

var configuration = Fluently.Configure()
    .Database(SQLiteConfiguration.Standard.UsingFile(AppConstants.PATH_FILENAME_DB))
    .Mappings(m => m.FluentMappings.AddFromAssemblyOf<...>())
    [...Mappings...]
    .Diagnostics(x => x.Enable());

My app.config:

<configSections>
  <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>

<log4net>
  <appender name="LogFileAppender" type="log4net.Appender.FileAppender">
    <param name="File" value="data/log/unprocessed.log"/>
    <param name="AppendToFile" value="true"/>
    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n"/>
    </layout>
  </appender>

  <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n"/>
    </layout>
  </appender>

  <logger name="NHibernate.SQL" additivity="false">
    <level value="ALL"/>
    <appender-ref ref="LogFileAppender"/>
  </logger>

  <root>
    <level value="INFO"/>
    <appender-ref ref="LogFileAppender"/>
  </root>
</log4net>

I can log stuff right after I initialize the main form:

log4net.Config.XmlConfigurator.Configure();
logger.Info("Here is a debug log!!");

And it works 100%. However I'm not able to get anything out of Nhibernate.

I've tried:

setting ShowSql() in my Fluent NHibernate config => SQL appears in VS console.

adding NHibernate logger

removing additivity

using ConsoleAppender instead of LogFileAppender (still no SQL in the output though I get regular logs from the application)

recompiling Fluent NHibernate, tried 3 different versions of log4net...

My Fluent Nhibernate mappings are good, my app is working perfectly without log4net.

I still am unable to log any queries from NHibernate... Not sure what is going on but if you have a clue I'll be happy to try it out!!!

Thanks!

Well I ended up finding the issue...

All my DLLs were located in /lib folder instead of the output folder.

Part of my app.config had this:

<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>
<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <probing privatePath="lib"/>
    <dependentAssembly>
      <assemblyIdentity name="System.Data" publicKeyToken="b77a5c561934e089"/>
      <bindingRedirect oldVersion="2.0.0.0" newVersion="4.0.0.0"/>
    </dependentAssembly>
  </assemblyBinding>
</runtime>

Putting log4net.dll in my output folder fixed the issue.
