ios - MT2002 : Failed to resolve assembly: System. 网络

Question

我跟踪了第三方程序集但没有得到任何线索。这是错误=> 编译为 native 代码

该错误只会在构建时出现，而不会在运行应用程序时出现。

这意味着您的依赖项之一(例如第 3 方二进制程序集)引用了 System.Web.dll。该程序集未随 Xamarin.iOS(任何版本)一起提供。

错误不会在模拟器上发生，因为:

• 默认情况下，它不使用链接器(它解析所有内容)；

• 它使用即时 (JIT) 编译器，因此只有当它尝试执行需要它的代码时才会命中缺少的程序集(或成员)；

• 在设备上运行所需的 Ahead-Of-Time (AOT) 编译器需要预编译所有内容，即在构建时(而非运行时)会检测到任何缺失
