选择新WPF项目时WPF设计器错误

当我选择一个新的WPF项目时，我会得到以下错误。
Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)

如果打开WPF编辑器时出现此错误，请尝试：
Studio.
- Install
- 打开Visual的第二个实例并尝试打开XAML。
- 关闭所有.xaml和.xml文件，关闭Visual，重新打开它并打开.xaml文件。
- 禁用工具->外接程序管理器
- 中的所有外接程序，以帮助修复XAML设计器。有一个已知的来自微软的反馈说，这应该会有所帮助。在这里下载(https://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=16827&wa=wsignin1.0)。*.msu是Windows或Windows 2008的修补程序。Windows或Windows 2003的*.exe。即使您使用64位计算机，您仍然需要x86修补程序，因为Visual 2008是一个32位的Silverlight工具、运行时、SDK、表达式混合。之后，修复Visual Studio.
- Reinstall Visual和.NET Framework.
如果没有工作，您将不得不重新安装操作系统。
