        }
    }
}

3.添加引用Divelements.SilverlightTools.dll
4.设置启动页面  <param name="windowless" value="true" />

以上是设置silverlight嵌套html文件

5.添加Sl.Input.dll引用

6.在xaml里添加<SlInpu:SLInput x:Name="mytxt1" Width="220" Height="150" Foreground="Red" FontSize="18" ></SlInpu:SLInput>

7.在百度网盘里搜索slInput.rar

8.有需要类库的朋友，请给我留言。。。。
