Unable to Write Logs into Azure with Nlog-CodePudding

I am Working on a DotNET core application and trying to implement Nlogs into Azure App service. While working on Local machine/Visual Studio, I am successfully able to generate Nlogs. However, when I publish the application to deploy on Azure Cloud, Nlogs do not generate at the Specified location.

This is the configuration which I did to publish the Nlog:- Release Configuration

After Deploying the application to cloud app service the configuration looks like:- Application settings

I do not receive any error and application works fine, Though I don't see any logs generated on app service.

In Visual Studio, Create .Net core Application Install Nuget Package Microsoft.Extensions.Logging.AzureAppServices, and Microsoft.Extensions.Logging.Console, version 3.1.2 for your project.

In Startup.cs, ConfigureServices method, add the below code:

 public void ConfigureServices(IServiceCollection services)
    {
        //other code

        //add the following code
        services.AddLogging(loggingBuilder =>
        {
            loggingBuilder.AddConsole();
            loggingBuilder.AddDebug();
            loggingBuilder.AddAzureWebAppDiagnostics();
        });
    }

Add the New Controller class and add the below code:

 private readonly ILogger<HomeController> _logger;
    public HomeController(ILogger<HomeController> logger)
    {
        _logger = logger;
    }
    public IActionResult Index()
    {
        _logger.LogInformation("**********first: hello, this is a test message!!!");
        _logger.LogInformation("**********second: hello, this is a test message!!!");
        return View();
    }

Publish the Application to Azure .
In Azure Portal navigate to --> App Service Logs, do the below settings
Navigate to "Log stream" in azure portal, then visit the web site, you can see the logs:
