logs messages not showing in application insights application for worker service

Question

This is my Program.Cs class public static void Main(string[] args) enter code here{ var services = new ServiceCollection(); var configuration = GetConfiguration(args);

        var serviceProvider = services
            .AddSingleton(configuration)
            .AddLogging(builder => builder
                .AddConsole()
                .AddFilter<ApplicationInsightsLoggerProvider>("Category", LogLevel.Information))
            .BuildServiceProvider();

        IHost host = Host.CreateDefaultBuilder(args)
                        .UseWindowsService()
                        .ConfigureServices((hostcontext, serviceProvider) =>
                        {                                
                            serviceProvider.AddHostedService<Program>();
                            serviceProvider.AddApplicationInsightsTelemetryWorkerService();// add instrumentation key                                
                        })
                        .Build();

        host.Run();
    }

This is my main service class

 protected async Task OnStart(string[] args)
        {
            _logger.LogInformation("start");
            using (var getDetailsOperation = _telemetryClient.StartOperation<RequestTelemetry>("operation"))
            {
                try
                {
                    this._telemetryClient.TrackTrace("start!!!");
                    //my code
                    _logger.LogInformation("Starting service ...");
}
catch(Exception ex){
  _logger.LogError(ex, OnStart - Exception Thrown");
                    this._telemetryClient.TrackTrace("Error !!!!!!!!!");
}
}
}

I want to log message for another classes also. Please help me out.
