PatternString no longer works in 3.0.0 (duplicate of #183)

[LuckyTil]

1. .Net 4.8 console app, works fine with log4net 2.0.17
2. App.Config

  <log4net>
        <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
            <lockingModel type="log4net.Appender.FileAppender+ExclusiveLock" />
            <file type="log4net.Util.PatternString" value="%property{LogFileName}" />
            <encoding value="utf-8" />
            <datePattern value="yyyy-MM-dd'.log'" />
            <staticLogFileName value="false" />
            <appendToFile value="true" />
            <rollingStyle value="Composite" />
            <maxSizeRollBackups value="50" />
            <maximumFileSize value="100MB" />
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
            </layout>
        </appender>
        <root>
            <level value="ALL" />
            <appender-ref ref="RollingFileAppender" />
        </root>
    </log4net>

3. On the XmlConfigurator.Configure() call

log4net:WARN Unable to set property [file] on object [log4net.Appender.RollingFileAppender] using value [%property{LogFileName}] (with acceptable conversion types)
log4net:ERROR Could not create Appender [RollingFileAppender] of type [log4net.Appender.RollingFileAppender]. Reported error follows.
