在VS 2015，Windows 7上为我工作，都有阴影：

Answer 2

这实际上是Windows 10上的默认行为（或外观）。

如果您添加对PresentationFramework.Aero.dll的引用（Project-＆gt; Add Reference-＆gt; Assemblies-＆gt; Framework in Visual Studio），您可以将Aero Windows 7样式应用于此ContextMenu ：

<Button Content="Click for ContextMenu" Width="166" HorizontalAlignment="Center" VerticalAlignment="Center" Height="100">
    <Button.ContextMenu>
        <ContextMenu x:Name="Test" HasDropShadow="True">
            <ContextMenu.Resources>
                <ResourceDictionary>
                    <ResourceDictionary.MergedDictionaries>
                        <ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml" />
                    </ResourceDictionary.MergedDictionaries>
                </ResourceDictionary>
            </ContextMenu.Resources>
            <MenuItem Header="File"/>
            <MenuItem Header="View"/>
            <MenuItem Header="Recent Files">
                <MenuItem Header="file1.txt"/>
                <MenuItem Header="file2.txt"/>
            </MenuItem>
            <MenuItem Header="Edit"/>
        </ContextMenu>
    </Button.ContextMenu>
</Button>
