It seems that log4net isn't looking for (or finding) my log4net.config,
which is in the test application executable folder - ie alongside the
app executable. My AssemblyInfo.cs for both the main application project
and the logging class project both have an XmlConfiguratorAttribute
defined, eg

 [assembly: log4net.Config.XmlConfigurator(ConfigFile =
"Log4Net.config", Watch = true)] 

As I understand it, this tells log4net to look in the app base
directory, which is where log4net.config is placed when the app is
built. However, if I copy the log4net.config to the path specified in
the trace above (ie c:\program files\Microsoft Visual studio
9\....\IDE\Log4Net.config) my logging works as required.

So what do I need to do to get log4net to look in the right place for
the config file?

TIA

Neil

What does log4net's internal debug message say:

 http://logging.apache.org/log4net/release/faq.html

Have you tried configuring log4net from within the client app's entry
point to verify your log4net.config is correct?

Subject: Problem getting Log4net to work

Can anybody spot what I am doing wrong? I'm probably doing something
stupid, but I've been banging my head against this for a few days and am
getting no further:

I have a solution comprising two projects, a client app and a logger
project. The logger project encapsulates calls to log4net. It has a line
in its AssemblyInfo file

    [assembly: log4net.Config.XmlConfigurator(ConfigFile =
"Log4Net.config", Watch = true)]

and static loggers and methods to call various loggers, eg

       private static readonly ILog bllDebugLog =
LogManager.GetLogger("Matrix.Trace"); 

and so on.

a Typical logging method in the logger code is

        public static void Trace(string message)
        {
            using (NDC.Push("TRACE"))
            {
              bllDebugLog.Debug(message);
            }
        }


In the same solution I have an application which references the above
assembly. The application makes calls to the static log methods, eg
logger.Trace("a message");

and the log4net.config file is in the executable directory of the
application (...\bin\debug and ...\bin\release).

It all seems straight out of the book, but try as I might I cannot get
log4net to log anything!

The bare bones of the log4net.config file is:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <log4net>


        <appender name="RollingFileAppenderROOT"
type="log4net.Appender.RollingFileAppender">
            <file value="c:\logs\MatrixROOT.log" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%m%newline" />
            </layout>
            <appendToFile value="true" />
            <maximumFileSize value="100KB" />
            <maxSizeRollBackups value="2" />
        </appender>


        <appender name="RollingFileAppenderTRACE"
type="log4net.Appender.RollingFileAppender">
            <file value="c:\logs\MatrixTRACE.log" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%m%newline" />
            </layout>
            <appendToFile value="true" />
            <maximumFileSize value="100KB" />
            <maxSizeRollBackups value="2" />
        </appender>


        <root>
            <appender-ref ref="RollingFileAppenderROOT" />
        </root>

        <logger name="Matrix.Trace">
             <!--this is for routine debug logging to a file--> 
            <level value="DEBUG" />
            <appender-ref ref="RollingFileAppenderTRACE" />
        </logger>

    </log4net>
</configuration>
