log4net - no log file produced - log4net

Question

I have this as my config file:
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="c:\\logging\\EwsSearch.log" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="-1" />
<maximumFileSize value="100KB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
</log4net>
<root>
<level value="ERROR" />
<appender-ref ref="RollingFileAppender" />
</root>
</configuration>
I then have in my C# code:
public class VsiEWSSearch
{
private static readonly ILog logger = LogManager.GetLogger(typeof(VsiEWSSearch));
public EWSResponse PdeProcessInquiry(int BusinessLineCode, int ClientCaseId, string callingApp)
{
XmlConfigurator.Configure(new System.IO.FileInfo("VSI.EWSSearch.config"));
logger.Error("This is an error");
No log file is produced even though I have adjusted permissions for the directory. What's wrong?

The root node has to be inside the log4net node. Depending on the type of configuration file you need to make some further adjustments:
If you have a standalone config file for log4net then you need to remove the configuration and configSections node. I also think that log4net is not going to find you configuration file unless you specify the full path (you can of course do that without hard-coding any path in your application).
If you are simply using app.config then you do not need further modifications, but you need to call the XmlConfigurator.Configure() method without any argument.
Note: You should call the XmlConfigurator.Configure() method only once in your application.
