WPF ShowDilaog() not found

Question

I used MahApps.Metro in this window, I want to display SecondMainWindow when I click on a button but ShowDilaog method is not found I when I add anew WPF window with out MahApps.Metro the ShowDilag() method will found and it works fine the problem is I can't ShowDilag() to display a window that contains MahApps.Metro what is wrong with that code ?

here is the code I used to display SecondMainWindow in a button click

SecondMainWindow SMainWindow = new SecondMainWindow();

        SMainWindow.ShowDialog();

This error will appear

A `MetroWindow` inherits from `Window` which indeed has a `ShowDialog` method. But looking at the code you have posted, the window in your XAML seems to be named "SecondMainWindo" (note the missing "w" at the end). So is `SecondMainWindow` really a window? — mm8, Apr 23 '20 at 12:44
And what is `SecoundMainWindow` in `Error CS1061 'SecoundMainWindow' does not contain a definition`? Note the `u`. — Clemens, Apr 23 '20 at 12:53

I Found the error SecoundMainWindow should inheritance from MetroWindow

public partial class SecoundMainWindow : MetroWindow
{
    public TestMainWindow()
    {
        InitializeComponent();
    }
}
