To configure log4net to generate a new file every day, you can use RollingFileAppender and set the DatePattern property to achieve this. Below is an example configuration:

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="log-file.log" />
  <appendToFile value="true" />
  <rollingStyle value="Date" />
  <datePattern value="'.'yyyyMMdd'.log'" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %level %logger - %message%newline" />
  </layout>
</appender>

<root>
  <level value="DEBUG" />
  <appender-ref ref="RollingFileAppender" />
</root>

In the above configuration, the RollingFileAppender specifies the name of the log file as log-file.log, and sets the rollingStyle to Date, indicating that new log files will be generated based on the date. The datePattern property sets the date format, which can be adjusted as needed.

With the above settings, log4net will generate a new log file every day and name it according to the date.
