我和Xamarin有几个小时的麻烦。我对代码进行了更改，并尝试一如既往地运行它。然后我得到一个错误，上面写着The "ResolveLibraryProjectImports" task failed unexpectedly。我尝试关闭我的Mac，Visual Studio，重建，删除obj和bin文件夹，清理解决方案，但对我来说什么都不起作用。有人能解决这个问题吗？如果有什么不同的话，我正在用MacOS Mojave开发Mac。我寻找以前的答案，但没有任何帮助。
完全错误

我自己发现了错误。我尝试了所有在评论中发布的内容，但都不起作用。我尝试重新安装visual studio，但也不起作用。所以我查看了Visual Studio的参考目录，发现在Android解决方案中存在对iOS解决方案的引用，而该引用不属于该包的一部分。所以我删除了它，更新了所有的包，一切都正常！
