crash - 在 Release模式下部署时，应用程序在 Windows Phone 上崩溃

Question

我们开发了一款支持 Android、iOS 和 Windows Phone 的 Xamarin Forms 应用。在 Debug模式下部署时，该应用程序可在所有三个操作系统上运行。

在 Release模式下部署时，它也适用于 Android 和 iOS。使用 Release模式部署时，它在 Windows Phone 8.1/10 上显示启动屏幕后立即崩溃，但奇怪的是，使用 Debug模式部署时一切正常。

原因是什么？

有没有办法查看应用日志来诊断崩溃原因？

嗨杰拉德/德米特里安，

非常感谢您的回复。请在下面找到输出窗口的内容。有 XamlParseException 但没有其他信息。我还附加了 Windows Phone 的“Decuments\Debug”文件夹中的调试日志。

我在这个问题上取得了一些进展。在我的案例中，FontFamily 属性引起了问题。因此，如果删除 fontfamily 属性并在 Release模式下运行应用程序，则不再抛出异常，但屏幕在设备上呈现的方式看起来与在 Debug模式下呈现的方式不同。

我已附上两个屏幕截图。我尝试按照 John 的指示在 Forms.Init 中添加第二个选项，但它给了我错误，因为该方法不支持第二个选项。

Debug mode screenshot

Release mode screenshot

对于上述行为，我有以下疑问:

• 为什么应用程序可以在 Debug模式下正常工作，而不能在 Release模式下正常工作模式？
• 为什么屏幕在 Debug模式下可以正确呈现，而在 Release模式？
• 为什么它不会像抛出的那样抛出任何错误 Release模式？
• 是否有遗漏的引用资料？不确定是否是这种情况，因为应用程序会抛出异常。

有什么建议吗？

Answer 1

一些简短的说明:

1.- 看起来“注册”按钮占据了整个屏幕高度，您是否尝试过为该按钮指定高度？像这样的东西:

Button.HeightRequest = "40";

2.- 您是否尝试过链接行为“不链接”？
