[WPF] HttpClientHandler SendAsync Call Never Getting HTTP Response Back

Question

Our project is developed with WPF C# with Target framework version of .Net Framework 4.6.2.

We were trying to do a POST call using HttpClientHandler, But we didn't get any response or the status back.
The application stays hanged, Didn't receiving any response. I am attaching my codes with sample URL for your reference. Help me with this issue.

The code hangs in the line
var result = await HttpCl.SendAsync(request);

We also didn't get any exception or error in the console.

Hi Magi,
i use this code without problems:

private async Task<AsyncObservableCollection<ContinentModel>> GetContinentModels()
{
  AsyncObservableCollection<ContinentModel> ReturnContinentModels = new AsyncObservableCollection<ContinentModel>();
  try
  {
    using (HttpClient httpClient = new HttpClient())
    {
      httpClient.DefaultRequestHeaders.Add("Accept", "application/json;charset=UTF-8");

      using (HttpResponseMessage HttpResponseMessage = await httpClient.GetAsync(string.Concat(_RootUrl, ""), HttpCompletionOption.ResponseHeadersRead).ConfigureAwait(false))
      {
        if (HttpResponseMessage.StatusCode == System.Net.HttpStatusCode.OK)
        {
          using (HttpContent HttpContent = HttpResponseMessage.Content)
          {
            string MyContent = await HttpContent.ReadAsStringAsync();
            var root = JsonConvert.DeserializeObject<RootObject>(MyContent);
            ReturnContinentModels = new AsyncObservableCollection<ContinentModel>(root.products);
          }
        }
      }
    }
  }
  catch (Exception ex)
  {
    Console.WriteLine(ex.Message);
  }
  return ReturnContinentModels;
}

var res = Task.Run() => GetVersionTest().Result;

private static async Task GetVersionTest()
{

var result = .....

if(result.StatusCode == HttpStatusCode.OK
{
var resp = result.Content.ReadAsStringAsync();
.....

}

}
