How to apply the same theme in all WPF windows using MahApps.Metro

I'm newer with WPF projects and I have a question about the component MahApps.Metro. I created a MainWindow and other windows in my project, my question is: How to apply the same theme in MainWindow to the others windows of the project? And, I must to apply the ResourceDictionary for all windows or exist any way to do this one time only?

Resource's in WPF work based on their available "scope". Check this article for a detailed explanation

Now Application(App.xaml) is in a higher scope to Window. Thus to share these MahApps control resources across your Window's just move the ResourceDictionary's to the Application.Resources scope

something like:

<Application.Resources>
  <ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
      <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colours.xaml" />
      <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
      <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
      <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
      <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
    </ResourceDictionary.MergedDictionaries>
  </ResourceDictionary>
</Application.Resources>

Now you no longer need to add these Dictionary's in each Window as they are available implicitly

In your App.xaml, set the ResourceDictionary property like this:

<Application.Resources>
    <ResourceDictionary Source="MyResourceDictionary.xaml"/>
</Application.Resources>

Notice that in order for the styles in your resource dictionary to be applied to all controls of that type, the style should NOT have a key. For example, a style defined like this:

<Style TargetType="{x:Type Button}">
    <Setter Property="Content" Value="This is the default button text"/>
</Style>

In the ResourceDictionary will cause all the buttons in the project to have a default value when you create them.
