在WPF中包装Windows窗体控件

Question

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity" 
        xmlns:cmd="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Extras.WPF45"
        xmlns:models="clr-namespace:Wordsearch_Editor.Models"
        xmlns:src="clr-namespace:Wordsearch_Editor"
        xmlns:Controls="clr-namespace:WpfRichText;assembly=WpfRichText" 
        xmlns:wf="clr-namespace:AxSHDocVw.AxWebBrowser;assembly=AxSHDocVw.AxWebBrowser"
        xmlns:resc="clr-namespace:Wordsearch_WYSIWYG_Editor.Resources"
        x:Name="window"
        Title="Wordsearch Editor" Height="500" Width="815" MinHeight="500" MinWidth="850">
    <Grid>
        <WindowsFormsHost>
            <wf:AxWebBrowser x:Name="mtbDate" Mask="00/00/0000"/>
        </WindowsFormsHost>
    </Grid>

我已经引用了AxWebBrowser和Windows窗体，但出于某种原因我无法将Windows窗体控件包装在WPF中。
