    How to send Ajax request, using HttpClient

    Well, Actually you can't send real AJAX request using HttpClient, but you can simulate it by adding XMLHttpRequest to request header like this:

    client.DefaultRequestHeaders.Add("X-Requested-With", "XMLHttpRequest");

    Here is a Helper method which requires Microsoft.AspNet.WebApi.Client nuget package:

        private async TResponse CreateHttpRequestAsync<TRequest, TResponse>(Uri uri, TRequest request)
            where TRequest : class
            where TResponse : class, new()
        {
            using (var client = new HttpClient())
            {
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Add("X-Requested-With", "XMLHttpRequest");
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                //client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", _bearerToken);
                var response = await client.PostAsJsonAsync(uri, request);
                if (response.StatusCode == HttpStatusCode.OK)
                {
                    var json = await response.Content.ReadAsStringAsync();
                    return JsonConvert.DeserializeObject<TResponse>(json);
                }
                else if(response.StatusCode == HttpStatusCode.Unauthorized)
                {
                    throw new UnauthorizedException();
                }
                else
                {
                    throw new InvalidOperationException();
                }
            }
    
        }

    POST http://localhost:8086/UK_60_Dev_Admin_Refactor/SelfRegistration/SelfRegistrationFormConfigurations HTTP/1.1
