c# WPF菜单条控制器

我试图通过创建一个WindowsFormsHost并添加一个菜单条作为它的孩子，在c#中使用WPF制作一个菜单栏。请注意，我使用WindowsFormsHost控制器的属性页添加菜单和菜单项。

当我完成时，项目构建并成功运行，但在生成的"xaml"文件中显示一些错误，设计器没有加载设计。

下面是生成的XAML代码

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:Forms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" x:Class="FrontEnd.AppMainWindow"
    Title="AppMainWindow" Height="351" Width="826">
<Grid>
    <WindowsFormsHost x:Name="menuStripHost" HorizontalAlignment="Left" Height="23" VerticalAlignment="Top" Width="818">
        <Forms:MenuStrip Visible="True" Name="appMainMenu">
            <Forms:MenuStrip.Items>
                <Forms:ToolStripMenuItem Text="File">
                    <Forms:ToolStripMenuItem.DropDownItems>
                        <Forms:ToolStripMenuItem ShortcutKeys="Ctrl+N" Text="New Project"/>
                        <Forms:ToolStripMenuItem ShortcutKeys="Ctrl+O" Text="Open Project"/>
                        <Forms:ToolStripMenuItem Text="Exit"/>
                    </Forms:ToolStripMenuItem.DropDownItems>
                </Forms:ToolStripMenuItem>
                <Forms:ToolStripMenuItem Text="View">
                    <Forms:ToolStripMenuItem.DropDownItems>
                        <Forms:ToolStripMenuItem Text="Configuration Window"/>
                    </Forms:ToolStripMenuItem.DropDownItems>
                </Forms:ToolStripMenuItem>
                <Forms:ToolStripMenuItem Text="Help">
                    <Forms:ToolStripMenuItem.DropDownItems>
                        <Forms:ToolStripMenuItem Text="User Manual"/>
                        <Forms:ToolStripMenuItem Text="Help"/>
                    </Forms:ToolStripMenuItem.DropDownItems>
                </Forms:ToolStripMenuItem>
            </Forms:MenuStrip.Items>
        </Forms:MenuStrip>
    </WindowsFormsHost>
</Grid></Window>

这里是错误

错误2不能将指定的值分配给集合。以下类型是预期的:"String".

同样的错误出现在所有带有标签"Forms:ToolStripMenuItem"的行

更新:尝试删除ShortcutKeys属性，但问题仍然存在(与上述错误相同)。下面是修改后的代码…
