我试图在Xamarin Forms Apps中启用“ Link All”。它已在Android中成功完成。但是，对于iOS版本，我遇到了运行时错误。
应用程序刚刚启动并崩溃。
在iOS→Main.cs→UIApplication.Main (args, null, "AppDelegate");
我该如何解决？
崩溃日志已附加。
Foundation.MonoTouchException已引发
抛出Objective-C异常。名称：NSInternalInconsistencyException
原因：应用程序窗口应具有根视图
应用程序启动结束时的控制器本机堆栈跟踪：0

最佳答案
我正在使用Link all assemblies而不是Link SDK assemblies only来减小APK / IPA文件的大小。
对于iOS和Android，它减少了约20MB。
对于iOS，我必须在所有[Preserve(AllMembers = true)]实现中添加dependency service。现在一切正常。
