我正在运行 VS 2010 和 Expression Blend 4 beta。我从提供的模板创建了一个 MVVM Light 项目,当我尝试在 VS 2010 设计器窗口中查看 MainWindow.Xaml 时,我得到一个 System.IO.FileLoadException。该模板已引用 System.Windows.Interactivity。以下是异常的详细信息:

System.IO.FileLoadException

System.NotSupportedException 尝试从网络位置加载程序集,这会导致程序集在以前版本的 .NET Framework 中被沙盒化。此版本的 .NET Framework 默认情况下不启用 CAS 策略,因此这种加载可能很危险。如果此加载不打算对程序集进行沙箱处理,请启用 loadFromRemoteSources 开关。有关详细信息,请参阅http://go.microsoft.com/fwlink/?LinkId=155569

是的,问题是在安装之前需要解封 zip 文件。

解封 zip 文件后,您可以安装在现有 DLL 之上,它们将被正确的版本覆盖。

问候,劳伦特

如果它仍然不起作用并且你已经完成了@LBugnion 告诉你要做的事情。然后它是propaly,因为您从网络位置运行项目。尝试将项目复制到一个 loval 驱动器(可能是您的桌面)。现在它应该工作了:D
