Question

我正在尝试在C＃XMAL WPF应用程序中设置材质设计。我在项目中添加了"Material Design In XAML"，之后我收到了以下错误：The property 'Content' can only be set once我的标记中会出现问题？我提供了以下错误的文件：

<Window x:Class="e621_fetch.MainWindow"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525"

    TextElement.Foreground="{DynamicResource MaterialDesignBody}"
    TextElement.FontWeight="Regular"

    Background="{DynamicResource MaterialDesignPaper}"

    <materialDesign:Card Padding="32" Margin="16"> //error on this line
              
        <TextBlock Style="{DynamicResource MaterialDesignTitleTextBlock}">My First Material Design App</TextBlock> //error on this line
            
    </materialDesign:Card> //error on this line
</Grid>
