EventLogs getting logged in .Net Runtime source rather than custom EventLog

Question

I have a .net core 6.0 web application wherein i have to write logs in a custom Event Log(TestApp). The logs are getting written but in .Net runtime source rather than the custom Event Log that I created.

Here's the event Log powershell script i executed

New-EventLog -Source TestApp -LogName Application

I have tried a couple of options that includes adding a LogName and application name attribute as mentioned below:

Configuring a custom event log for log4net Log4Net EventLogAppender Not Logging To Custom Event Log

Also have tried restarting system & Event viewer but the logs are written in .Net runtime source only.

Here's the Log4 net config file:

<?xml version="1.0" encoding="utf-8" ?>
<log4net xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" debug="true">
    <root>
        <level value="ALL" />
        <appender-ref ref="EventLog" />
    </root>
    <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
        <file value="c:\temp\TestApp.log" />
        <appendToFile value="true"/>
        <maximumFileSize value="1000KB"/>
        <maxSizeRollBackups value="10"/>
        <layout type="log4net.Layout.PatternLayout">
            <conversionPattern value="%date %level %logger.%method [%line] - MESSAGE: %message%newline %exception%newline" />
        </layout>
    </appender>
    <appender name="EventLog" type="log4net.Appender.EventLogAppender,log4net" >
        <logName value="Application" />
        <applicationName value="TestApp" />
        <layout type="log4net.Layout.PatternLayout,log4net">
            <conversionPattern value="%date %level %logger.%method [%line] - MESSAGE: %message%newline %exception%newline" />
        </layout>
    </appender>
</log4net>

Here's log.release.config part

<?xml version="1.0" encoding="utf-8"?>
<log4net xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" debug="true" xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

    </root>
    <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
        <file value="#{LogFileFolder}#\TestApp.log" xdt:Transform="Replace"/>
        <appendToFile value="true"/>
        <maximumFileSize value="1000KB"/>
        <maxSizeRollBackups value="10"/>
        <layout type="log4net.Layout.PatternLayout">

        </layout>
    </appender>
</log4net>

Hostbuilder section for log:

public class Program
{
    public static void Main(string[] args)
    {
        var host = CreateHostBuilder(args)
            .UseServiceProviderFactory(new AutofacServiceProviderFactory())
            .ConfigureAppConfiguration((context, config) =>
            {
                var environment = context.HostingEnvironment;

                config.SetBasePath(Directory.GetCurrentDirectory());

                config.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                    .AddJsonFile($"appsettings.{environment.EnvironmentName}.json", optional: true,
                        reloadOnChange: true);

                Configuration = config.Build();

                HostingEnvironment = context.HostingEnvironment;
            })
            .ConfigureLogging(logging =>
            { 
               logging.AddLog4Net("log4net.config", true); 
               logging.AddEventLog(eventLogSettings => eventLogSettings.SourceName = "TestApp");
            })
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
                webBuilder.UseIISIntegration();
            })
            .Build();

        host.Run();
    }

    public static IConfiguration? Configuration { get; set; }
    public static IHostEnvironment? HostingEnvironment { get; set; }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args);
}

Finally was able to change the source to a custom App name. The AddEventLog() takes in the default .NetRuntime as the source name if not provided. Updated the program.cs file .ConfigureLogging() section along with the snap shot for reference.

.ConfigureLogging(logging =>
           {
               logging.AddLog4Net("log4net.config", true);
               logging.AddEventLog(eventLogSettings => eventLogSettings.SourceName = "TestApp");
           })
