Logging is not generated after upgrading to 3.0 (duplicate of #183)

[jayluc2]

After updating from version 2.0.15 to 3.0.0, our logging isn't being written. I've managed to isolate this to using GlobalContext properties within the file name, although I suspect anywhere properties are used are also a problem. I've boiled our code down to the minimal set needed to reproduce the issue:

Program.cs:

static void Main(string[] args)
{
    log4net.GlobalContext.Properties["mycustomusername"] = "me";
    
    Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
    FileInfo logfile = new FileInfo(configuration.FilePath);
    XmlConfigurator.ConfigureAndWatch(logfile);

    var _log = log4net.LogManager.GetLogger(typeof(Program));

    long value = 0;
    while (true)
    {
        _log.Debug($"New value is: {value++}");
        Thread.Sleep(1000);
    }
}

App.Config:

  <log4net>
    <appender name="RollingAppender" type="log4net.Appender.RollingFileAppender">
      <file type="log4net.Util.PatternString" value="f:\temp\%property{mycustomusername}TestAppLog.log"/>
      <appendToFile value="true"/>
      <preserveLogFileNameExtension value="true"/>
      <rollingStyle value="Composite"/>
      <datePattern value=".yyyyMMdd"/>
      <maximumFileSize value="1KB"/>
      <countDirection value="1"/>
      <maxSizeRollBackups value="20"/>
      <staticLogFileName value="false"/>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date %-5level [%thread] - %message%newline"/>
      </layout>
    </appender>
    <root>
      <level value="DEBUG"/>
      <appender-ref ref="RollingAppender"/>
    </root>
  </log4net>

This message appears in the console window:
log4net:WARN Unable to set property [file] on object [log4net.Appender.RollingFileAppender] using value [f:\temp%property{mycustomusername}TestAppLog.log] (with acceptable conversion types)

Hi @jayluc2,

thanks for reporting.
This bug was fixed in https://www.nuget.org/packages/log4net/3.0.1-preview.2
We will release the final 3.0.1 tomorrow.
