Nel file Application.xaml ho dichiarato il seguente style
codice:
   <Style x:Key="stile_ListBoxItem" TargetType="{x:Type ListBoxItem}">
            <Setter Property="FocusVisualStyle"
                            Value="{x:Null}" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ListBoxItem}">
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsSelected"
                                             Value="True">
                                <Trigger.EnterActions>
                                    <BeginStoryboard>
                                        <Storyboard>
                                            <DoubleAnimation To="2"   
                                                                     Storyboard.TargetName="scale"
                                                                     Storyboard.TargetProperty="ScaleY" />
                                            <DoubleAnimation To="2"                      
                                                                     Storyboard.TargetName="scale"
                                                                     Storyboard.TargetProperty="ScaleX" />
                                        </Storyboard>
                                    </BeginStoryboard>
                                </Trigger.EnterActions>
                                <Trigger.ExitActions>
                                    <BeginStoryboard>
                                        <Storyboard>
                                            <DoubleAnimation To="1"
                                                                     
                                                                     Storyboard.TargetName="scale"
                                                                     Storyboard.TargetProperty="ScaleY" />
                                            <DoubleAnimation To="1"
                                                                     
                                                                     Storyboard.TargetName="scale"
                                                                     Storyboard.TargetProperty="ScaleX" />
                                        </Storyboard>
                                    </BeginStoryboard>
                                </Trigger.ExitActions>
                            </Trigger>
                        </ControlTemplate.Triggers>
                        <ContentPresenter>
                            <ContentPresenter.LayoutTransform>
                                <ScaleTransform ScaleY="1"
                                                        x:Name="scale" />
                            </ContentPresenter.LayoutTransform>
                        </ContentPresenter>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
nella window ho la seguente list box
codice:
<ListBox Margin="12,78,273,12" Name="ListBoxRisultati" />

tento di impostare attraverso le proprietà lo style di ItemContainerStyle ma non riesco a vedere lo style dichiarato al livello applicazione.

Dove sbaglio?
