how to set up basic AsyncCommand with Task in xamarin form

Tools: I am using Xamarin.form MVVM.

Question: How do I set up basic AsyncCommand command with Task?

Debug: I am not getting any error, when I click on button, Displaybox alert doesnt show up. I check and addcommand method is not getting runned on tap.

Bind: I also have bind View with ViewModel

 BindingContext = new ProductViewModel();  

I watched a tutorial by microsoft and there seem to be working just fine. Did I missed something?

View Page

<Button Text="Add" Command="{Binding AddCommand}" />  

ViewModel Page

public class ProductViewModel : INotifyPropertyChanged      {         ...        public AsyncCommand AddComamnd { get; }                 public ProductViewModel()        {          ...          AddComamnd = new AsyncCommand(OnAddComamnd);         }      public async Task OnAddComamnd()      {          await App.Current.MainPage.DisplayAlert("Alert", "You have been alerted", "OK");        // I have also tried both (App and Application) neither works      }  }
