我使用Xamarin（最新版）和Visual Studio 2015创建了 Cross-Plattform - 应用程序 - 项目（原生共享）。
我按照教程“Hello Android”完成了它，但在构建项目时我会收到以下错误消息：
严重级代码描述项目文件行抑制状态 错误CS0117 'Resource.Id'不包含的定义 'CallButton' HelloApp.Droid C：\ Users \ username \ documents \ visual studio 2015 \ Projects \ HelloApp \ HelloApp \ HelloApp \ HelloApp.Droid \ MainActivity.cs 26 Active
（与其他小部件相同）
我尝试了不同的API级别/重新安装的sdks和软件包，如this Question中所述，但它对我不起作用。我为不同的API级别安装了Android Build Tools并卸载了其他API，但这不会改变一件事。
我也试过了这个问题中陈述的solution并尝试多次清理和重建解决方案，我还删除了xamarin-zips文件夹中的拉链。每次都会编译Resource.designer.cs并且看起来很好......而且Build Action对所有文件都是正确的。
有人可以帮忙吗？
PS：在Mac上它运行得很好，但我想在Windows上用Visual Studio开发......

我也有这个错误 我做的只是保存文件，它修复了！希望能帮到你。
答案 1 :(得分：1)
1。删除“ {yourAPPlocation} \ Resources \ Resource.designer.cs”中的所有内容。
2。重建整个项目。
3。复制整个“ {yourAPPlocation} \ Resources \ Resource.designer.cs”新生儿并粘贴到 “ {yourAPPlocation} \ obj \ Debug \ 81 \ designtime \ Resource.designer.cs”。
然后它起作用了！
希望在您的项目上也能成功。
