我已经安装了 Silverlight 4 beta 工具包并创建了一个新的 silverlight 业务应用程序。根本不做任何更改，当我尝试在设计器视图中查看 Mainpage.xaml 时，我在设计器窗口中收到以下错误：

System.Reflection.TargetInvocationException
Exception has been thrown by the target of an invocation.

运行基本的 silverlight 项目会导致 IE 崩溃（鉴于上述错误，这不足为奇）。更糟糕的是，我加载了一个现有的 Silverlight 3 应用程序并尝试在那里检查 Mainpage.xaml 并得到相同的错误（帮助！）。

我现在已经在两台完全不同的电脑上尝试了这个，并且遇到了完全相同的问题。有任何想法吗？
