MessageBox error

I tried to implement the code below in a Windows Phone 8.1 project, it had already been implemented in Windows Forms successfully.

What should I change to be valid for Windows Phone 8.1? 

private void reset_Click(object sender, RoutedEventArgs e)
{
    const string message = "Voce deseja voltar o jogo ao seu estado normal ?";
    const string caption = "Reset";
    var result = MessageBox.Show(message, caption,
                                 MessageBoxButtons.YesNo,
                                 MessageBoxIcon.Question);

    if (result == DialogResult.No)
    {

    }
    else { this.Close(); /*re-estabeleçe valores*/ }

    }

Displays the following error:

  

The name 'MessageBox' does not exist in the current context

In the new Windows Phone 8.1 APIs you need to use the await MessageDialog().ShowAsync() of Windows.UI.Popups. In your case, it would look like this: 

var mensagem = new MessageDialog("Sua mensagem");
await mensagem.ShowAsync();

Windows Phone is not the same as Windows Forms. Your code should look something like this: 

private async void reset_Click(object sender, RoutedEventArgs e)
{
    const string message = "Voce deseja voltar o jogo ao seu estado normal ?";
    const string caption = "Reset";

    MessageBoxResult result = MessageBox.Show(message, caption, MessageBoxButton.OKCancel);

    if (result == MessageBoxResult.Cancel)
    {

    }
    else { this.Close(); /*re-estabeleçe valores*/ }

}

All this with: 

using System.Windows;

in the header of the file.
