Why log4net doesn't log nhibernate information - asp.net-mvc

Question

My Visual Studio Solution contains:
[DLL] Sol.DataAccess (NHibernate sessionManager)
[DLL] Sol.Core (Models and Repository)
[MVC] Sol.WebMvc (Controler, View)
All my application contains are (nhibernate.dll [v3.0] and log4net.dll[v1.2.10])
I have 3 configs:
web.config:
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821" requirePermission="false" />
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
</configSections>
</configuration>
nhibernate.config:
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory name="...">
<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
<property name="connection.connection_string_name">...</property>

<property name="cache.use_query_cache">true</property>
<property name="cache.provider_class">NHibernate.Caches.SysCache2.SysCacheProvider, NHibernate.Caches.SysCache2</property>
<mapping assembly="..."/>
</session-factory>
</hibernate-configuration>
and log4net.config:

var factory = NHibernateSessionManager.ConfigureFromFile(Server.MapPath("~/hibernate.config"));

}
in my test controller i have:
public class TestController : BaseController
{
[NHibernateSession]
public ActionResult Index()
{
Logger.Error("fake error", new Exception());
}
}
In my log file - Logs/Logs.txt:
2011-03-11 18:19:23,097 [8] ERROR System.Web.Mvc.Controller [(null)] - fake error
System.Exception: Exception of type 'System.Exception' was thrown.
QUESTION:
Why log4net doesn't log NHibernate information (info, debug ....)
Aren't the versions of these dlls compatible?

Answer 1

I have create an empty ASP.Net MVC3 project. and loss much time trying to fix this issue.
And I find VS2010 bug. Visual Studio 2010 don't copy dll's in bin when you refer it in project.
I put log4net.dll manual in my bin folder and work fine. (Interesting thing is that Logger.Error("fake error") work fine without log4net.dll in bin folder ...)

Answer 2

First off: you speak of "log4net.config", but you don't include that anywhere. The way you configure it in web.config, you should actually include a section called <log4net> inside your web.config, not as a separate file.
If you don't want it in your web.config, you can remove the log4net related sections altogether and add the following line to yur global.asax.cs:
log4net.Config.XmlConfigurator.ConfigureAndWatch(
New FileInfo(Server.MapPath("~/yourreleativepath/log4net.config")))
Also, possibly you miss the priority setting, not entirely sure this helps, but give it a try:
<root>
<priority value="DEBUG"/>
<appender-ref ref="Console"/>
<appender-ref ref="FileAppender"/>
<appender-ref ref="AdoNetAppender"/>
</root>
Also, to finetune (because you'll get a lot messages), use something like this:
<logger name="NHibernate.SQL">
<level value="DEBUG"/>
</logger>
<logger name="NHibernate">
<level value="WARN"/>
</logger>
On nhibernate.info you'll find a full example.
