c# - 链接程序集意外失败 (Xamarin.ios.dll)

Question

当我尝试在 Release模式下编译时，出现错误，而在 Debug模式下效果很好。我正在尝试存档 APK，但由于 Xamarin.ios.dll 错误而无法存档

我尝试删除 obj 和 bin 文件夹并单独重新编译它们，它确实有效，但是当我尝试存档时，出现错误，要求我检查是否可以编译该项目。

此外，Xamarin.iOS 引用了 Xamarin.Android，对吗？

Answer 1

由于 APK 适用于 Android，因此您绝对不应该在项目中引用 Xamarin.iOS。检查您的 Android 引用，并确保右键单击您的解决方案，转到“选项”、“配置”、“配置映射”，然后在构建 Android 时取消选中您的 iOS 项目(即在“任何 CPU”中构建时)
