Question

我有UserControl RoundButton.xaml：

<UserControl x:Class="app.controls.RoundButton"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d">
    <Grid>
        <Border x:Name="_Border" Background="Cyan" CornerRadius="2" >
            <Border.Effect>
                <DropShadowEffect x:Name="_Shadow" BlurRadius="0" ShadowDepth="1" Direction="270" Color="White"/>
            </Border.Effect>
           <Button x:Name="_Button" Content="RoundButton" Background="{x:Null}" BorderThickness="0" Padding="10,0,10,0"/>
        </Border>     
    </Grid>
</UserControl>

RoundButton.xaml.cs：

namespace app.controls
{
    public partial class RoundButton : UserControl
    {
        public RoundButton() { InitializeComponent(); }

        [EditorBrowsable(EditorBrowsableState.Always), Browsable(true), DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
        public new Brush Background
        {
            get { return _Border.Background; }
            set { _Border.Background = value; }
        }
    }
}

我希望能够在Blend中更改Background属性。

当我将Background属性定义为新属性时，在Blend中更改它不会影响我的按钮。当我将其定义为覆盖时，我得到错误：Error 1 'app.controls.RoundButton.Background.get': cannot override inherited member 'System.Windows.Controls.Control.Background.get' because it is not marked virtual, abstract, or override

覆盖UserControl属性以便能够在Blend中修改它们的最佳方法是什么？

修改
我找到的解决方法是重命名所有RoundButton属性并阻止在Blend中显示的UserControl属性表单：

public new Brush _Background
{
    get { return _Border.Background; }
    set { _Border.Background = value; }
}
[Browsable(false)]
public new Brush Background { get; set; }

覆盖UserControl的Background属性
