将Android App升级到MvvmCross 6.4.1导致在Visual Studio 2017上构建失败

问题描述 投票：1回答：1

正如标题所示，我正在升级现有Xamarin.Android项目的依赖项。 Android项目将MvvmCross用于许多跨平台代码（我们也支持其他平台）。作为此升级的一部分，我们将从MvvmCross 6.2.2迁移到6.4.1。

但是，升级库后，使用Visual Studio 2017构建项目时，将不再按预期构建项目。我收到的错误消息如下所示。我曾尝试清洁和重建无济于事。该项目使用Visual Studio 2019构建，但遇到奇怪的行为;这甚至在升级我们的依赖项之前就已经发生。

关于解决此问题的任何建议，我们将不胜感激。提前非常感谢您！

从MvvmCross 6.3.1升级到MvvmCross 6.4.1并使用VS 2017后，我们也出现了类似错误：
