c# – 应用程序在发布模式下崩溃,而不是在调试模式下崩溃 – Xamarin Forms

我正在构建一个跨平台的应用程序,我想将它发布给测试人员,但是当我在发布模式下部署它时它不起作用.就例外而言,我没有得到任何.如问题中所述,它在调试模式下工作.该应用程序只是闪屏和崩溃.我通过测试仙女运行原始应用程序并获得此异常：

我无法向您展示源代码,但我在新的测试解决方案中重现了错误.
Here是包含测试项目的存储库的链接.它只是一个使用MVVM和Xamarin Forms的项目.

解决方法:

通过手动删除整个解决方案中的所有obj文件夹和所有bin文件夹来修复它.

编辑：再次回来,现在这个修复不起作用！
