Xamarin App does nothing after await the GetAsync method

Question

I have created a class, in Xamarin Forms, that requests to a web API about the details of countries. Right now, I am testing only with a country.

However, once the line

HttpResponseMessage response = await client.GetAsync(uri);

is executed, the app does nothing additional.

In order to validate if the app executes other instructions after this line, I have included additional lines to write the sequence into the device log.

All the lines before the previous instruction are written into the log and none of them after this instruction.

On the other hand, the screen of the device remains blank, without insert the Label created by code.

Here is the code of the class and the method that consumes the API.

using Android.Util;
using System.Net.Http;
using System.Threading.Tasks;

class Country
{
    public int iIdCountry { get; set; }
    public string sCountryName { get; set; }
    public string sCountryIsoCode { get; set; }
    public string sCountryPhoneCode { get; set; }
    public bool bCountryContainsPrefix { get; set; }
    public bool bCountryActive { get; set; }

    private static readonly HttpClient client = new HttpClient();

    public static async Task<Country> GetCountryAsync(int id)
    {
        string baseUri = new BaseUri().baseUri;
        string suffixUri = "/CountriesApi/GetItem/" + id;
        var uri = baseUri + suffixUri;
        string tag = "myapp";
        Country country = null;

        HttpResponseMessage response = await client.GetAsync(uri);
        Log.Info(tag, "Response received");

        if (response.IsSuccessStatusCode)
        {
            country = await response.Content.ReadAsAsync<Country>();
            Log.Info(tag, "Country received");
        }

        Log.Info(tag, "Country returned");
        return country;
    }
}

This is the component that makes the call to the previous class:

using Android.Util;
using System;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;

namespace EnubexMobile.Views
{
    [XamlCompilation(XamlCompilationOptions.Compile)]

    public partial class Start : ContentPage
    {
        public Start()
        {
            var stackLayout = new StackLayout();
            string tag = "myapp";

            InitializeComponent();
            Log.Info(tag, "Started");

            var country = Country.GetCountryAsync(1).GetAwaiter().GetResult();
            Log.Info(tag, country.sCountryName);

            var label = new Label() { Text = country.sCountryName };
            Log.Info(tag, "Label created");

            stackLayout.Children.Add(label);
            Log.Info(tag, "Label added");
        }

        private void InitializeComponent()
        {
            throw new NotImplementedException();
        }
    }
}

The idea is to insert a label into the StackLayout with the name of the country received from the API.

Could someone help me to understand what I am missing here?

Thanks !
