将鼠标悬停在效果上并在IsSelected（UserControl，WPF）

Question

我想在鼠标进入时悬停效果，在鼠标移开时恢复透明。但是在UserControl IsSelected（viewmodel属性）时禁用此动画。

我有一些有效的代码，但不是我想要的，并且有一些问题。当鼠标进入和开始播放动画时，用户控件将白色背景和快速动画设置为我需要的颜色。当IsSelected为true时，此动画也播放我不需要。

<UserControl.Resources>
        <Style x:Key="ContentStyle" TargetType="{x:Type ContentControl}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ContentControl}">

                        <!-- Content -->
                        <Border x:Name="background" Background="#2b2d33">

                            <!-- Click to open message -->
                            <Border.InputBindings>
                                <MouseBinding MouseAction="LeftClick" Command="{Binding GoToChat}" />
                            </Border.InputBindings>

                            <Grid x:Name="container" Background="Transparent">

                                </Grid.ColumnDefinitions>
