how to configure static log file name with compositely named roll backups

Question

I used this config but a date is always added to the current file ('log.20130805.0.log').

<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="Logs/logFile.log" />
    <appendToFile value="true" />
    <preserveLogFileNameExtension value="true" />
    <rollingStyle value="Composite" />
    <datePattern value=".yyyyMMdd" />
    <maximumFileSize value="10MB" />
    <countDirection value="1"/>
    <maxSizeRollBackups value="-1" />
    <staticLogFileName value="false" />
    <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%date [%thread] %-5level %logger - %message%newline" />
    </layout>
</appender>

The result of that config is :

log.20130805.0.log
log.20130805.1.log
log.20130805.2.log
log.20130805.3.log

What I get with staticLogFileName = true is :

log.log
log.1.log
log.2.log
log.3.log

What I want is :

log.log
log.20130805.1.log
log.20130805.2.log
log.20130805.3.log

I know I'm late to the party, but I believe I have figured out how to use a composite RollingFileAppender properly. I'm posting it here for posterity, in case anyone stumbles upon this in a search:

<appender name="rollingfileappender" type="log4net.Appender.RollingFileAppender">
    <file value="C:\Logs\logfile.log" />
    <datePattern value=".yyyyMMdd" />
    <preserveLogFileNameExtension value="true" />
    <appendToFile value="true" />
    <rollingStyle value="Composite" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="100Kb" />
    <staticLogFileName value="true" />
    <layout type="log4net.Layout.DynamicPatternLayout">
        <conversionPattern value="%[level] - %date - %message" />
    </layout>
</appender>

The key here is:

<preserveLogFileNameExtension value="true" /> and <staticLogFileName value="true" />

When your current log files are being appended, you'll see:

logfile.log
logfile.1.log
logfile.2.log
etc...

Once the new day hits, those should be renamed to:

logfile.20200623.log
logfile.20200623.1.log
logfile.20200623.2.log
etc...

and you'll have a new logfile.log, still catching your current logs.
