自从 1 周以来，我发现了 Xamarin 框架，我的工作是让 Android 应用程序运行。 iOS应用程序之前已经推出了。
我必须首先处理一些 NuGet 包依赖项，但现在我得到的唯一例外是：

我在这里看到很多帖子，似乎是图标问题，但是我检查了项目中的所有资源定义，资源名称，一切似乎都很好。
此问题是否可能是由错误的引用（例如 Xamarin Forms 或 Iconize）引起的？或者这可能只是因为缺少资源？
我已经清理了我的解决方案，更新或降级了我的软件包，但没有任何作用..
我还必须表明我使用F#而不是C#进行开发。我的观点是用 XAML 做出的。
终于找到问题所在了。
首先，我必须在“构建操作”字段中为所有资源文件设置“AndroidResource”（选择资源时请参阅属性）
其次，我不能使用 A 到 Z、0 到 9 和“_”等其他字符来命名我的资源。
这就是我为解决问题所做的 -
我解决类似问题的方法是清理项目、重建并运行它。 这是我的一位同事给我的一个很好的建议。
您是否尝试过删除 C:\Users\YOURUSER\AppData\Local\Xamarin\ 中的内容
当我重命名、插入或替换可绘制路径中的任何文件时，这种情况总是发生在我身上。
每当我做这样的事情时，我都会遵循以下步骤：
