XAML 页面在 Visual Studio 2008 上显示异常消息
我正在开发一个 WPF 应用程序，该应用程序已经运行良好一段时间了。最近，尽管应用程序运行良好，但 XAML 用户控件在 Visual Studio 2008 上无法正确显示。它显示一长串异常消息。为了方便起见，下面列出了一些消息。
调用目标已引发异常。

I am working on a WPF App which has been working fine for some time. Recently, the XAML user controls do not show up properly on Visual Studio 2008 though the Application runs fine. It shows a long list of Exception messages. For convenience, some of the messages are listed below.
