Apply ResourceDictionary to Pages in Frame in WPF

I have a Window in WPF which simply contains a Frame element. The Frame displays a Page; which Page is displayed changes based on user interaction.

<Window x:Class="MyWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Height="720" Width="1280">
    <Grid>
        <Frame Source="{Binding Source={StaticResource MainPageIntent}, Path=Path}"/>
    </Grid>
</Window>

I would like all Pages that appear in that Frame to share a common Resource Dictionary so that they may all be styled in a common way.

Right now I have something like this in every page that this Window loads:

<Page.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/ResourceDictionaries/BaseControlStyles/MenuStyle.xaml"/>

I was hoping that I might just be able to set the resource dictionary on the Window, and they would "inherit" those resources, but that does not appear to be the case. I tried something like this, but the styles found in MenuStyle.xaml are not applied the the controls inside the Page loaded by the Frame:

<Window x:Class="MyWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Height="720" Width="1280">
    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/ResourceDictionaries/BaseControlStyles/MenuStyle.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
        <Frame Source="{Binding Source={StaticResource MainPageIntent}, Path=Path}"/>
    </Grid>
</Window>

Is there are way to define styles at the Window level such that all pages loaded in child Frames will use those styles?

Note: I do not want to apply these styles to ALL windows in my application, so putting this ResourceDictionary in my App.xaml does not appear to be a valid solution.

If you want to write it once to avoid code duplicates, you can write it in code behind. On frame ContentRendered you can write a code to add resource to the page which is being loaded.

<Frame Name="fr_View" ContentRendered="fr_View_ContentRendered"/>


private void fr_View_ContentRendered(object sender, System.EventArgs e)
{
     ResourceDictionary myResourceDictionary = new ResourceDictionary();
     myResourceDictionary.Source = new Uri("Dictionary1.xaml", UriKind.Relative);
     (fr_View.Content as System.Windows.Controls.Page).Resources.MergedDictionaries.Add(myResourceDictionary);
}
