我正在尝试在Windows窗体应用程序的主窗口中添加一个新选项卡，但是当我尝试运行应用程序（{1}}时，我当前遇到异常。例外情况给出了描述：
未处理的类型＆＃39; System.Windows.Markup.XamlParseException＆＃39;发生在PresentationFramework.dll
中附加信息：＆＃39;在类型＆＃39; RiviamAgent.MainWindow＆＃39;上调用构造函数。匹配指定的绑定约束引发异常。＆＃39;行号＆＃39; 3＆＃39;和行位置＆＃39; 9＆＃39;。
应用程序的XamlParseException was unhandled是：

所做的唯一编辑是添加标记：
XML在＆＃39;预览＆＃39;在Visual Studio中显示在XAML文件中写入的XML的面板，我可以看到我所做的更改是正确显示的，即窗口显示两个选项卡 - ＆＃39;应用程序＆＃39; ＆安培; ＆＃39;浏览器＆＃39;但由于某些原因，我在尝试运行应用程序时收到<TabControl>
<TabItem Header="Application" >
...
</TabItem>
<TabItem Header="Browser"></TabItem>
</TabControl>
。
我在SO上发现的大多数相关问题似乎都表明我需要在我的C＃中为我的构造函数添加一个XamlParseException块 - 我已经尝试过了，但它没有做到差异，并且鉴于自我的申请上次工作以来我唯一改变的是try-catch文件，我本以为这个问题与XML有关 - 任何人都有任何建议吗？
修改
点击了查看详细信息＆＃39;在异常窗口中，它所抱怨的行似乎是我.xaml类的声明：
Browser.cs错误说：
在类型＆＃39; Agent.MainWindow＆＃39;上调用构造函数。匹配指定的绑定约束引发异常。＆＃39;行号＆＃39; 3＆＃39;和行位置＆＃39; 9＆＃39;。＆＃34;}
这是上面引用的partial class Browser{
行...
修改
进一步研究了一下，似乎在调用partial class Browser{时抛出了异常...在整个解决方案中对MainWindow的唯一调用是XAML的第一行文件：
MainWindow我如何处理这样的XML异常？
