Postasync works with UWP but breaks on android project

Question

Hi

Been having issue with Xamarin Cross Platform Android Project. I am using Wep Api Project to call a service from xamarin portable project.

 

//Portable project
var auth = new SigninModel
            {
                Username = username,
                Password = password

            };



var stringContent = new StringContent(JsonConvert.SerializeObject(auth), Encoding.UTF8, "application/json");
            var response = await Client.PostAsync("http://localhost:54019/api/AuthenticationApi/Login", stringContent);


//WebApi
        [System.Web.Http.Route("api/AuthenticationApi/Login/")]
        [System.Web.Http.AcceptVerbs("GET", "POST")]
        [System.Web.Http.HttpPut]
        public DBResult Login(AuthenticationModel model)
        {
            SupervisorModel result = null;
            bool hasError = false;
            string errorText = "";

            if (ModelState.IsValid)
            {
                result = Authentication.AuthenticateUser(model.Username, model.Password);

            }
            else
            {
                hasError = true;

            }

            return new DBResult { status = !hasError ? "Success" : "Fail", descripText = BadRequest(ModelState).ToString(), data = new SupervisorModel { Id = result.Id, Name = result.Name, Surname = result.Surname } };

        }
