In this blog article I will discuss how to enable log4net in application. Log4net is used to create a log in application. Please follow below steps to enable log4net.

Step 1- Install log4net from nuget package manager.
Step 2- Add following code in your config file.

    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  <log4net debug="true">
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="logs\log.txt" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
      <level value="DEBUG" />
      <appender-ref ref="RollingLogFileAppender" />

Step 3- Create instance of log4net to write logs.

 private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

Step 4- Now start write logs in your code.
