Question

我最近将我的解决方案从Xamarin Forms 2.5更新到了3.1。我已经在不同的应用程序（UWP，IOS，Android）上安装了Prism.DryIoc.Forms 7.0.0.396软件包。自从使用UWP更新以来，一切正常，但是当我尝试启动我的Android项目时，出现此错误：

我以前从未处理过LinkAssemblies。我的Android选项中的链接设置为“无”。我的MainActivity.cs（Android）和App.xaml.cs中的代码未更改且正确。

Dan Siegel回答了：

此问题是由您更改的主要版本引起的。现在，您需要回滚到2.X，我们将很快更新到DryIoc 3

Xamarin Forms更新到3.1后，“ LinkAssemblies”任务意外失败
