Concurrently awaiting multiple asynchronous calls with independent continuations

Question

There are several scenarios where I need to invoke multiple asynchronous calls (from the same event handler) that can proceed independently of each other, with each one havi

Answer 1

private async void button_Click(object sender, RoutedEventArgs)
{ 
    var nameTask = GetNameAsync();
    var cityTask= GetCityAsync();
    var rankTask= GetRankAsync();

    System.Threading.Tasks.Task.WaitAll(nameTask, cityTask, rankTask);

    nameTextBox.Text = nameTask.Result;
    cityTextBox.Text = cityTask.Result;
    rankTextBox.Text = rankTask.Result;
}
