推荐答案

尝试卸载支持库，然后重新安装.

Try uninstalling the Support Libraries and then reinstalling them again.

如果这不起作用，请尝试进入 C:\Users\{Your User}\AppData\Local\Xamarin 并删除其中的所有文件夹.然后在 Visual Studio 中进行清理和重建.

If that doesn't work, try going into C:\Users\{Your User}\AppData\Local\Xamarin and delete all folders in there. Then do a Clean and Rebuild in Visual Studio.
