Silverlight设计器未处理的异常（IOException）。无法打开xaml页面

Question

当我使用Silverlight 4创建一个新的Silverlight应用程序（C＃，如果这很重要）并在设计器中打开MainPage.xaml时，我会收到一个Unhandled Exception has occurred。

Stack details如下：

System.IO.FileNotFoundException
Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.

请帮助解决此问题。

在安装了Visual Studio 2010 Service Pack 1之后，经过大量的脑力激荡搜索和点击试用后，这些东西对我有用。
