        <Frame x:Name="contentFrame" >

        <Frame.ContentTransitions>
            <TransitionCollection>
                    <NavigationThemeTransition>
                        <DrillInNavigationTransitionInfo />

Answer 1

but I could not change the font color

您可以使用 TextBlock 控件作为 NavigationViewItem 的内容，然后可以为 TextBlock 控件设置 Foreground 属性。

请参考以下代码示例：

<NavigationView Grid.Row="1" x:Name="nvSample" PaneDisplayMode="Top"
          IsSettingsVisible="True" IsBackButtonVisible="Collapsed">
        <NavigationView.MenuItems>
            <NavigationViewItem Tag="Home_Page" HorizontalAlignment="Stretch" Height="38" Margin="12,0,0,0" VerticalAlignment="Stretch">
                <NavigationViewItem.Content>
                    <TextBlock Text="Menu Item1" Foreground="Red"></TextBlock>
                </NavigationViewItem.Content>
            </NavigationViewItem>
            <NavigationViewItem Content="Instalpage" Tag="Install_Page" />
            <NavigationViewItem Content="Menu Item3" Tag="SamplePage3" />
            <NavigationViewItem Content="Menu Item4" Tag="SamplePage4" />
        </NavigationView.MenuItems>
        <Frame x:Name="contentFrame" >

            <Frame.ContentTransitions>
                <TransitionCollection>
                    <NavigationThemeTransition>
                        <DrillInNavigationTransitionInfo />
                    </NavigationThemeTransition>
                </TransitionCollection>
            </Frame.ContentTransitions>
        </Frame>
        <NavigationView.PaneFooter>
            <StackPanel Orientation="Horizontal">
                <!--<NavigationViewItem Icon="SelectAll" Content="Select all" Foreground="White" />
                <NavigationViewItem Icon="Help" Content="Help" />-->
            </StackPanel>
        </NavigationView.PaneFooter>
    </NavigationView>

Answer 2

NavigationViewItem 确实有一个名为 Foreground 的属性，它对我有用

<NavigationView.MenuItems>
        <NavigationViewItem Content="Menu Item1" Foreground="Black" Tag="Home_Page" Height="38" HorizontalAlignment="Stretch" Margin="0,0,0,0" VerticalAlignment="Stretch"  />
        <NavigationViewItem Content="Instalpage" Foreground="Black" Tag="Install_Page" />
        <NavigationViewItem Content="Menu Item3" Foreground="Black" Tag="SamplePage3" />
        <NavigationViewItem Content="Menu Item4" Foreground="Black" Tag="SamplePage4" />
</NavigationView.MenuItems>
