Xamarin Forms 更新到 3.1 后 "LinkAssemblies" 任务意外失败

Question

我最近将我的解决方案从 Xamarin Forms 2.5 更新到 3.1。我已经在不同的应用程序（UWP、IOS、Android）上安装了包 Prism.DryIoc.Forms 7.0.0.396。自从使用 UWP 更新后，一切都按预期进行，但是当我尝试启动我的 Android 项目时，出现此错误：

Severity    Code    Description Project File    Line    Suppression State
Error       The "LinkAssemblies" task failed unexpectedly.

我以前从未接触过 LinkAssemblies。我的 Android 选项中的链接设置为 none。我的 MainActivity.cs (Android) 和 App.xaml.cs 中的代码没有更改并且是正确的。

This issue is caused by your changing major versions. For now you'll need to roll back to 2.X, we'll be updating to DryIoc 3 soon
