Dennis,
The error seems new to me, because I had encountered lot of issues while
implementing the log4Net in my app.
Please check the below option , it might help you..
1.In your web.config enable the log4net enable
<add key="log4net.Internal.Debug" value="true"/>
After </system.web>
<system.diagnostics>
<trace autoflush="true">
<listeners>
<add name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="c:\\logerror.log" />
</listeners>
</trace>
</system.diagnostics>
2. <configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler,
log4net,Version=1.2.11.0, Culture=neutral, PublicKeyToken=669e0ddf0bb1aa2a"/>
</configSections>
3.In you config ,is this the full path
<file value="logfile.txt" />
make sure you have full write permission.
4.I was using EventLog appender , so I gave permission to create the log for
the users.
5.mention
using log4net;
using log4net.Config;
using System.Reflection;
using System.Diagnostics.Eventing;
6.try
public static readonly ILog log =
LogManager.GetLogger(typeof(ErrorLogging).Name);
instead of
log =
log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
Let me know if it helps.
Thanks,

Subject: Logger not working in an ASP.Net environment only works with full trust
I've made a simple .NET 4 Web Application in VS2010, and added a reference to
log4net 1.2.11.0 (latest).
In this project I've made a Logger class:
public static class Logger
{
private static readonly log4net.ILog log;
static Logger()
{
try {
log4net.Config.XmlConfigurator.Configure();
log =
log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
}
catch (Exception e)
{
System.Diagnostics.Debug.Write(e.ToString());
}
}
public static void LogInfo(string information)
{
log.Info(information);
}
public static void LogError(string erroMessage, Exception ex)
{
log.Error(erroMessage, ex);
}
public static void LogWarnings(string warningText)
{
log.Warn(warningText);
}
public static void Fatal(string fatalText)
{
log.Fatal(fatalText);
}
}
When I call this Logger class (Logger.Fatal("Test");) in a Full trust
environment, everything works correct. However, when I change the trust level
to High (or Medium) it fails with the following exception:
System.Reflection.TargetInvocationException: Exception has been thrown by the
target of an invocation. ---> System.TypeLoadException: Inheritance security
rules violated while overriding member:
'log4net.Util.ReadOnlyPropertiesDictionary.GetObjectData(System.Runtime.Serialization.SerializationInfo,
System.Runtime.Serialization.StreamingContext)'. Security accessibility of the
overriding method must match the security accessibility of the method being
overriden.

When I include the log4net project to the solution, I get the exception when
creating an instance of the default LogRepository:
rep = (ILoggerRepository)Activator.CreateInstance(repositoryType); on line 412
of DefaultRepositorySelector.cs
this is my web.config:
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>

<compilation debug="true" targetFramework="4.0" />
<trust level="High" />
</system.web>
<log4net debug="true">

<layout type="log4net.Layout.PatternLayout">

</layout>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="RollingFileAppender" />
</root>
</log4net>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
Other people suggest to add requirePermission="false" to the section, but then
the debugger won't attach to the application pool.
I hope someone can help me out of this problem.

Dennis Minderhoud
