Question

当我选择一个新的WPF项目时，我收到以下错误。

Loading this assembly would produce a different grant set from other instances. (Exception from HRESULT: 0x80131401)

如果在打开WPF编辑器时出现此错误，请尝试：

打开Visual Studio的第二个实例并尝试打开XAML。
关闭所有.xaml和.xml文件，关闭Visual Studio，重新打开它并打开.xaml文件。
禁用工具中的所有加载项 - ＆gt;加载项管理器
在Visual Studio中“重置所有设置”。
安装有助于修复XAML设计器的CLR补丁（KB963676）。有一个来自微软的已知反馈表明这应该有所帮助。在此下载（https://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=16827&wa=wsignin1.0）。 * .msu是Windows Vista或Windows Server 2008的补丁。* .exe适用于Windows XP或Windows Server 2003.即使您使用的是64位计算机，仍需要x86补丁，因为Visual Studio 2008是32位的应用
卸载所有Silverlight工具，运行时，SDK，Expression Blend。在此之后，修复Visual Studio。
重新安装Visual Studio和.NET Framework。

如果无效，则必须重新安装操作系统。
