Trouble enabling log4net in Fluent NHibernate -

i need in configuring log4net , fluent nhibernate. seems log4net starting, i'm not getting information nhibernate/fluent nhibernate. want information debug faulty mapping.

configuration in app.config

<appender name="consoleappender" type="log4net.appender.consoleappender" >   <layout type="log4net.layout.patternlayout">     <param name="header" value="[header]\r\n" />     <param name="footer" value="[footer]\r\n" />     <param name="conversionpattern" value="%d [%t] %-5p %c %m%n" />   </layout> </appender>  <root>   <level value="all" />   <appender-ref ref="logfileappender" />   <appender-ref ref="consoleappender" /> </root> <logger name="nhibernate"     additivity="false">   <level value="all"/>   <appender-ref ref="consoleappender"/> </logger> 

here's how launch log4net , configuration.

        log4net.config.xmlconfigurator.configure();          fluentconfiguration cfg = fluently.configure()             .database(sqliteconfiguration.standard.showsql().inmemory())             .diagnostics(x => x.enable());         dbctx.source = new sessionsource(cfg.buildconfiguration()                                                 .properties, new psmodel()); 

the exception i'm getting in last line on cfg.buildconfiguration(). don't entries in log on how mapping went, though.

thank in advance help.

if wanting see messages in output window in visual studio should use following instead:

<appender name="consoleappender" type="log4net.appender.traceappender" > 

also see log messages may want throw nhibernate spits out logfileappender well:

<logger name="nhibernate"     additivity="false">   <level value="all"/>   <appender-ref ref="consoleappender"/>   <appender-ref ref="logfileappender"/> </logger>
