Question

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。在没有进行任何更改的情况下，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（鉴于上述错误并不令人惊讶）。更糟糕的是，我加载了一个现有的Silverlight 3应用程序并尝试检查那里的Mainpage.xaml并得到了同样的错误（帮助！）。

我现在在两个完全不同的电脑上尝试了这个并且得到了完全相同的问题。有什么想法吗？

Silverlight 4 beta + RIA服务 - 第一步是TargetInvocationException
