c# - Xamarin Profiler 使应用程序从一开始就崩溃

Question

我有一个使用 MVVM Cross 开发的 Xamarin 应用程序，我正在尝试分析它。

但是，第一个屏幕一出现，应用程序就会崩溃。

接近崩溃的 Xamarin Profiler 控制台:

我已经关注这个很长时间了，但我无法弄清楚为什么 Xamarin Profiler 会导致我的应用程序崩溃。该应用在调试/ Release模式下表现良好。

虽然他们错过了他们的 Xamarin Profiler documentation 中的这一步您应该在 Android 选项 中禁用使用共享运行时 选项，因为他们在他们的 Profiling documentation 中确实建议这样做.

这对我有用。
