ListView Selected Item Style Override - wpf

Question

I have a WPF ListView that I'm trying to apply a custom style too... primarily I want to make the background of the listview box transparent with no border... and I want to override the highlighted and selected item styles. The default highlight is a semi-transparent blue and the selected item is grey. I'd like to override these in order to customize them. I've followed several threads and tutorials... including this one but, my highlight and selected items remain in the default style. Here's what I have.
<UserControl.Resources>
<ResourceDictionary>
<Style x:Key="ListViewStyle" TargetType="ListView">
<Setter Property="Background" Value="Transparent"></Setter>
<Setter Property="BorderThickness" Value="0"></Setter>
<Setter Property="BorderBrush" Value="Transparent"></Setter>
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red" />
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Green" />
</Style.Resources>
</Style>
</ResourceDictionary>
</UserControl.Resources>
....
<ListView Style="{StaticResource ListViewStyle}" ItemsSource="{Binding Path=Items}" ScrollViewer.VerticalScrollBarVisibility="Disabled" SelectedItem="{Binding Path=DataContext.Current" >
<ListView.ItemTemplate>
<DataTemplate DataType="local:Cases">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
<!-- Some UI Controls Here -->
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>

This approach of trying to override the system colours doesn't work on Windows 8 and later.
You need to modify the ControlTemplate of the ListViewItem container.
You can copy the default template into your XAML markup by right-clicking on the ListView in design mode in Visual Studio or in Blend and choose Edit Additional Templates->Edit Generated Item Container (ItemContainerStyle) and then edit it as per your requirements by for example changing the Color properties of the SolidColorBrushes:
<ListView ItemsSource="{Binding Path=Items}" SelectedItem="{Binding Path=DataContext.Current" >
<ListView.Resources>
<Style x:Key="FocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<SolidColorBrush x:Key="Item.MouseOver.Background" Color="Red"/>
<SolidColorBrush x:Key="Item.MouseOver.Border" Color="#a826A0Da"/>
<SolidColorBrush x:Key="Item.SelectedInactive.Background" Color="#3DDADADA"/>
<SolidColorBrush x:Key="Item.SelectedInactive.Border" Color="#FFDADADA"/>
<SolidColorBrush x:Key="Item.SelectedActive.Background" Color="#3D26A0DA"/>
<SolidColorBrush x:Key="Item.SelectedActive.Border" Color="#FF26A0DA"/>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="SnapsToDevicePixels" Value="True"/>
<Setter Property="Padding" Value="4,1"/>
<Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListViewItem}">
<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
