错误"ResolveLibraryProjectImports"任务意外失败

Question

尝试使用Xamarin在VS2017中编译Android项目时,我遇到了错误.我得到一个字符串类型不允许错误,其中一个建议是更新我所有的Xamarin.Android引用.我发现了一个处理Xamarin.Core的observable的人,所以我安装了它.从那时起,我一直在解决分辨率错误.我已经尝试删除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

我刚刚在另一个问题上回答了这个问题（/sf/answers/3134638461/）。

关键在于，如果您的解决方案保存到路径较长的位置，则可能会导致某些文件的路径超出 Windows 的最大路径（260 个字符）

尝试将解决方案移至 C 或 D 的根（如果有的话）。
