WinUI - defualt style

Question

Hello,

My app.xaml has the following:

<Application.Resources>
<ResourceDictionary>
<x:Double x:Key="ContentDialogMaxWidth">1400</x:Double>
<ResourceDictionary.MergedDictionaries>
<controls:XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>

The second bold line override the first bold line - the first line does not change the value. if I don't use the second bold line, other stuff fail (without exact error details- only parsing error) but I need to change the default style.
can you please help?
Thanks,

It works for me (Windows App SDK 1.1.0, Windows 10 21H1) with :

 <Application.Resources>  
        <ResourceDictionary>  
            <ResourceDictionary.MergedDictionaries>  
                <!--<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />-->  
                <!-- Other merged dictionaries here -->  
                <XamlControlsResources>  
                    <XamlControlsResources.MergedDictionaries>  
                        <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />  
                        <ResourceDictionary>  
                            <x:Double x:Key="ContentDialogMaxWidth">1400</x:Double>  
                        </ResourceDictionary>  
                    </XamlControlsResources.MergedDictionaries>  
                </XamlControlsResources>  
            </ResourceDictionary.MergedDictionaries>  
            <!-- Other app resources here -->             
        </ResourceDictionary>  
    </Application.Resources>
