在wpf应用程序中添加功能区控件时,出现此异常。有人可以给我一些建议如何克服它吗?在我的xaml代码中,功能区被添加到最后一个选项卡中,如下面的代码所示。一切正常,添加功能区后问题开始出现。
<Window

<Menu Margin="0" Grid.Row="0" VerticalAlignment="Top" Background="#FFEAF1FB">

最佳答案
1。
添加对System.Windows.Controls.Ribbon
的引用
2。
将名称空间添加到您的XAML文件
xmlns:ribbon="clr-namespace:System.Windows.Controls.Ribbon;assembly=System.Windows.Controls.Ribbon"
关于c# - XamlObjectWriterException:无法创建未知类型'{http://schemas.microsoft.com/winfx/2006/xaml/presentation}Ribbon',我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/49194792/
