android - 错误 "ResolveLibraryProjectImports"任务意外失败

Question

尝试使用 Xamarin 在 VS2017 中编译 Android 项目时出现错误。我收到了不允许的字符串类型错误，其中一项建议是更新我所有的 Xamarin.Android 引用。我找到了一个处理 Xamarin.Core 可观察对象的工具，所以我安装了它。从那以后，我一直收到分辨率错误。我尝试删除 obj 和 bin 目录并重新启动 vs 和我的笔记本电脑。

这是错误的文本

问题来了:System.IO.PathTooLongException:指定的路径、文件名或两者都太长。完全限定文件名必须少于 260 个字符，目录名必须少于 248 个字符。

尝试将您的项目移动到另一个位置，例如“C:/”，或者更改项目名称以获得更简短的名称
