当尝试为我的Android应用构建发行版APK时，出现错误：
"The "LinkAssemblies" task failed unexpectedly."
我已经尝试了在其他论坛帖子和在线上可以找到的所有内容，但没有任何效果。 （我见过的帖子包括-对xamarin.ios的引用，最低目标android版本必须为21或更高。这两个都已检查并且没有引起问题。）
我在这里https://docs.microsoft.com/en-us/xamarin/xamarin-forms/troubleshooting/questions/android-linkassemblies-error检查了常见情况 但我仍然遇到错误。

我可以看到它与对“ System.Configuration.ConfigurationException”的引用有关，但是在我的项目中找不到对此的任何引用。
