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

问题描述

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）上安装了包 Prism.DryIoc.Forms 7.0.0.396。自从使用 UWP 更新以来，一切都按预期工作，但是当我尝试启动我的 Android 项目时，它会收到以下错误：

Severity    Code    Description Project File    Line    Suppression State

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 中的代码没有更改并且是正确的。

解决方案

丹西格尔回答了这个问题：

此问题是由您更改主要版本引起的。现在你需要回滚到 2.X，我们很快就会更新到 DryIoc 3
