UWP, App.Xaml: Override default brushes

Question

If I need to override a color in a brush, I would set it into App.xaml like this:

<Application.Resources> 

     ...

       <ResourceDictionary>
                <ResourceDictionary.ThemeDictionaries>
                    <ResourceDictionary x:Key="Light">
                        <SolidColorBrush x:Key="PivotHeaderForegroundUnselectedBrush" Color="#A7A9AC" />
                        <SolidColorBrush x:Key="PivotHeaderForegroundSelectedBrush" Color="Black" />
                    </ResourceDictionary>
                </ResourceDictionary.ThemeDictionaries>
            </ResourceDictionary>

         ...
</Application.Resources>

The editor underlines <ResourceDictionary> saying: "Each dictionary entry must have an associated key".

How can solve this?

What is holding the ResourceDictionary (what's the parent object/XAML)? — Igor Ralic, Oct 02 '15 at 16:55
I cannot reproduce the issue when I included only the xaml code in app.xaml. Can you reproduce the issue in a blank UWP project with these xaml code only? Maybe you have more things there? It will be helpful if you can provide the repro steps with a new blank project. — Alan Yao - MSFT, Oct 06 '15 at 17:19

I solved the problem, thanks to @Alan Yao - MSFT. Maybe you have more things there?, I had something else, written into the ResourceDictionary. By making ResourceDictionary parent of everything inside Application.Resources, I solved the problem.

The ResourceDictionary has to be placed inside application resources:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.ThemeDictionaries>
            <ResourceDictionary x:Key="Light">
                <SolidColorBrush x:Key="PivotHeaderForegroundUnselectedBrush" Color="#A7A9AC" />
                <SolidColorBrush x:Key="PivotHeaderForegroundSelectedBrush" Color="Black" />
            </ResourceDictionary>
        </ResourceDictionary.ThemeDictionaries>
    </ResourceDictionary>
</Application.Resources>

@misiMe Ok, I had answered before you have added comment to your question. So no reason for point down. — user2250152, Oct 05 '15 at 10:25
