尝试安装 Visual Studio Community 2019 扩展时出错

Question

我只是进入扩展>管理扩展>更新，单击“全部更新”，然后关闭 Visual Studio。 安装就报错了，网上搜了下不知道是什么问题。

已经完全修复并重新安装了visual studio

有什么帮助吗？这是错误日志。

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

删除文件资源管理器搜索找到的所有“Microsoft.VisualStudio.Validation.dll”并重新安装visual studio后，它工作了！
