Nuget package not working: Basic reproduceable example

[danammeansbear]

Hello all, I just tried to create a c# console program using the nuget package latest version and it is not working.

Console program
`
using System;
using log4net;
using log4net.Config;
using System.IO;
using System.Reflection;
using System.Net.Http;
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;
using System.Threading.Tasks;
using log4stash;

[assembly: XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

namespace ELKTest
{
internal class Program
{
private static readonly ILog logger = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

    static async Task Main(string[] args)
    {
        // Enable log4net internal debugging
        log4net.Util.LogLog.InternalDebugging = true;
        log4net.Config.XmlConfigurator.Configure();

        var logger = LogManager.GetLogger("elk_test");

        // Ignore SSL certificate errors (not recommended for production)
        //var handler = new HttpClientHandler();
        //handler.ServerCertificateCustomValidationCallback = (HttpRequestMessage, X509Certificate2, X509Chain, SslPolicyErrors) => true;
        //var client = new HttpClient(handler);

        //var request = new HttpRequestMessage(HttpMethod.Post, "server.com:9200/elk_test/_doc");
        //request.Headers.Add("Authorization", "Basic password");
        //var content = new StringContent("some message");
        //request.Content = content;

        //var response = await client.SendAsync(request);
        //response.EnsureSuccessStatusCode();
        //Console.WriteLine(await response.Content.ReadAsStringAsync());

//the above is test code used to make sure I can send messages to elk. Had to modify the code produced by postman because of certificate errors.
try
{
// Ensure log4net is configured
var logRepository = LogManager.GetRepository(Assembly.GetEntryAssembly());

            // Reflectively modify the HttpClientHandler of the ElasticSearchAppender
            var log4stashAppender = (ElasticSearchAppender)LogManager.GetRepository().GetAppenders()[0];
            var clientField = typeof(ElasticSearchAppender).GetField("_client", BindingFlags.NonPublic | BindingFlags.Instance);
            if (clientField != null)
            {
                var httpClient = (HttpClient)clientField.GetValue(log4stashAppender);
                var customHandler = new HttpClientHandler
                {
                    ServerCertificateCustomValidationCallback = (HttpRequestMessage, X509Certificate2, X509Chain, SslPolicyErrors) => true
                };
                var customClient = new HttpClient(customHandler);
                clientField.SetValue(log4stashAppender, customClient);
            }

            log4stashAppender.ActivateOptions();

            // Log messages
            logger.Debug("This is a DEBUG message.");
            logger.Info("This is an INFO message.");
            logger.Warn("This is a WARN message.");
            logger.Error("This is an ERROR message.");
            logger.Error("kaboom!", new ApplicationException("An error occurred"));
            Console.WriteLine("Log messages have been sent to Elasticsearch....maybe....");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error occurred: " + ex.Message);
        }
    }
}

}
