Good Day everyone. I'm developing a Cross Platform Application in Xamarin.Forms when I encounter this error "Are you missing a using directive or an assembly reference". My project is working fine before I install a Nuget package (Circle Image View in Xamarin), but when I uninstall it (without changing a single line of code) the said error started to appear. I tried to Build, Rebuild it but still it does not work. Anything I can do to fix this? Any help will be appreciated. Thanks a lot.

错误1:

找不到类型或名称空间名称"Xamarin"(您是否缺少using指令或程序集引用?)

推荐答案

在我的环境中遇到这样的错误时，我会执行以下操作:

When I got an error like this on my Environment, I do following:

1. 在Visual Studio中清洁解决方案
2. 关闭VisualStudio
3. 手动(从整个解决方案中)删除所有"bin"和"obj"文件夹
4. 手动删除"packages"文件夹
5. 重新启动VisualStudio
6. 全部重建

在大多数情况下，这可以解决此引用问题(就我而言)

In most cases, this solves this reference-problems (in my case)
