Style all ListViewItem in UWP app

Question

I wanted to change the selected background color of an ListViewItem. Now I noticed, that the default value doesn't get overridden.

<Style TargetType="ListViewItem">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ListViewItem">
                <ListViewItemPresenter
                  ContentTransitions="{TemplateBinding ContentTransitions}"
                  SelectionCheckMarkVisualEnabled="True"
                  CheckBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}"
                  CheckBoxBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}"
                  DragBackground="{ThemeResource ListViewItemDragBackgroundThemeBrush}"
                  DragForeground="{ThemeResource ListViewItemDragForegroundThemeBrush}"
                  FocusBorderBrush="{ThemeResource SystemControlForegroundAltHighBrush}"
                  FocusSecondaryBorderBrush="{ThemeResource SystemControlForegroundBaseHighBrush}"
                  PlaceholderBackground="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}"
                  PointerOverBackground="{ThemeResource SystemControlHighlightListLowBrush}"
                  PointerOverForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}"
                  SelectedBackground="{StaticResource YellowBrush}"
                  SelectedForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}"
                  SelectedPointerOverBackground="{ThemeResource SystemControlHighlightListAccentMediumBrush}"
                  PressedBackground="{ThemeResource SystemControlHighlightListMediumBrush}"
                  SelectedPressedBackground="{ThemeResource SystemControlHighlightListAccentHighBrush}"
                  DisabledOpacity="{ThemeResource ListViewItemDisabledThemeOpacity}"
                  DragOpacity="{ThemeResource ListViewItemDragThemeOpacity}"
                  ReorderHintOffset="{ThemeResource ListViewItemReorderHintThemeOffset}"
                  HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"
                  VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
                  ContentMargin="{TemplateBinding Padding}"
                  CheckMode="Inline"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

In this post it is mentioned, that one has to override the ItemContainerStyle property. But this can only be done on the ListView itself.

Is there no option to overwrite the style for all ListViewItem in the app?

PS: One could overwrite the brushes like e.g.

<SolidColorBrush x:Key="SystemControlHighlightListAccentLowBrush" Color="Yellow" />

but I only want to style the ListViewItem and not affect other styles.

Edit:

Because I got

Visual Studio requires a newer version of WIndows to display this content. Please update to Windows 10 Anniversary Edition (10.0.14393.0) or later.

I set the target version to 10240. This is what I found in the App.xaml after creating the copy as stated by Thomas Schneiter:

<Application.Resources>
    <Style TargetType="ListViewItem">
        <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
        <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
        <Setter Property="TabNavigation" Value="Local"/>
        <Setter Property="IsHoldingEnabled" Value="True"/>
        <Setter Property="Padding" Value="12,0,12,0"/>
        <Setter Property="HorizontalContentAlignment" Value="Left"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="MinWidth" Value="{ThemeResource ListViewItemMinWidth}"/>
        <Setter Property="MinHeight" Value="{ThemeResource ListViewItemMinHeight}"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListViewItem">
                    <ListViewItemPresenter 
                        CheckBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}" 
                        ContentMargin="{TemplateBinding Padding}" 
                        CheckMode="Inline"
                        ContentTransitions="{TemplateBinding ContentTransitions}" 
                        CheckBoxBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}" 
                        DragForeground="{ThemeResource ListViewItemDragForegroundThemeBrush}" 
                        DragOpacity="{ThemeResource ListViewItemDragThemeOpacity}" 
                        DragBackground="{ThemeResource ListViewItemDragBackgroundThemeBrush}" 
                        DisabledOpacity="{ThemeResource ListViewItemDisabledThemeOpacity}"
                        FocusBorderBrush="{ThemeResource SystemControlForegroundAltHighBrush}" 
                        FocusSecondaryBorderBrush="{ThemeResource SystemControlForegroundBaseHighBrush}"
                        HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" 
                        PointerOverForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}" 
                        PressedBackground="{ThemeResource SystemControlHighlightListMediumBrush}" 
                        PlaceholderBackground="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}" 
                        PointerOverBackground="{ThemeResource SystemControlHighlightListLowBrush}" 
                        ReorderHintOffset="{ThemeResource ListViewItemReorderHintThemeOffset}" 
                        SelectedPressedBackground="{ThemeResource SystemControlHighlightListAccentHighBrush}" 
                        SelectionCheckMarkVisualEnabled="True" 
                        SelectedForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}" 
                        SelectedPointerOverBackground="{ThemeResource SystemControlHighlightListAccentMediumBrush}" 
                        SelectedBackground="{ThemeResource SystemControlHighlightListAccentLowBrush}" 
                        VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Application.Resources>

Now I tried to override SelectedBackground, but the changes don't get applied.

You can right click on any ListView in the Designer View and select Edit Additional Templates -> Edit Generated Item Container (Item Container Style) -> Edit a Copy.
Then select Apply to all and Application to automatically insert a global copy into the app.xaml.
