Step-by-step Setup of log4net with bug fixes for working with VS2010

Step 1: Download log4net
I used log4net for logging in my C# application, however, the log4net version downloaded from the official website at the time has a number of bugs, I have removed those bugs and have it running smoothly with my C# application within the VS2010, the bug-fixed package can be downloaded from:

http://www.4shared.com/zip/VkND-sg4/log4net-1211.html

Step 2: Configure log4net in C# application
To configure log4net, after downloading the bug-fixed version from the above link and unzip it, add the project to your VS2010 solution in the IDE, then double-click your app.config from your VS2010 IDE to open it. Replace its content with the following:

<?xml version="1.0"?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net" />
  </configSections>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
  </startup>
  <appSettings file="">
    <clear />
    <add key="log4net.Internal.Debug" value="true" />
    <add key="ClientSettingsProvider.ServiceUri" value="" />
  </appSettings>
  <log4net>
    <root>
      <level value="DEBUG" />
      <appender-ref ref="LogFileAppender" />
    </root>
    <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
      <param name="File" value="log-file.txt" />
      <param name="AppendToFile" value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>
  </log4net>
  <system.web>
    <membership defaultProvider="ClientAuthenticationMembershipProvider">
      <providers>
        <add name="ClientAuthenticationMembershipProvider" type="System.Web.ClientServices.Providers.ClientFormsAuthenticationMembershipProvider, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" serviceUri="" />
      </providers>
    </membership>
    <roleManager defaultProvider="ClientRoleProvider" enabled="true">
      <providers>
        <add name="ClientRoleProvider" type="System.Web.ClientServices.Providers.ClientRoleProvider, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" serviceUri="" cacheTimeout="86400" />
      </providers>
    </roleManager>
  </system.web>
</configuration>

The above configuration works with .net 4.0 and log the errors and events to the file named log-file.txt. Next open the Program.cs and add the following line as the first in the Main() method:

log4net.Config.XmlConfigurator.Configure();

Step 3: Use log4net to do the logging
Now open one of your class (e.g. let's say the class name is Animal and has a method called Bark()), add the following line to where you declare your member variables:

private static ILog log = LogManager.GetLogger(typeof(Animal));

Now in the method Animal.Bark(), add the following line to log event:

log.Log("some message");

or the following line to log error:

log.Error("some error");
