在发布模式下部署时，应用程序在 Windows Phone 崩溃
App crashing on Windows Phone when deployed in Release mode
我们开发了支持 Android、iOS 和 Windows Phone 的 Xamarin Forms 应用程序。在调试模式下部署时，该应用程序可在所有三个操作系统上运行。
在发布模式下部署时，它还在 Android 和 iOS 上工作。当使用 Release 模式部署时，在 Windows Phone 8.1/10 上显示启动画面后立即崩溃，但奇怪的是，当使用 Debug 模式部署时一切正常。
这是什么原因？
有没有办法查看应用日志来诊断崩溃原因？

我在这个问题上取得了一些进展。 FontFamily 属性 在我的案例中引起了问题。因此，如果在 Release 模式下删除 fontfamily 属性 和 运行 应用程序，则不再抛出异常，但屏幕在设备上的呈现方式与在 Debug 中呈现的方式完全不同模式。
我附上了两个屏幕截图。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，我有以下问题：
- 为什么应用程序在调试模式下正常工作而不是在发布模式下
模式？
- 为什么屏幕在调试模式下正确呈现而不是
发布模式？
- 为什么它不像它抛出的那样抛出任何错误
释放模式？
- 是否有遗漏的参考资料？不确定是否属于这种情况，因为应用程序会抛出异常说明。
有什么建议吗？
几个简短的笔记：
1.- 看起来“注册”按钮占用了所有屏幕高度，您是否尝试过为此按钮指定高度？类似于：
Button.HeightRequest = "40";
2.- 您是否尝试过链接行为 "Don't link"？
我的问题终于解决了。如果您遇到同样的问题，请在下面找到解决方案。
项目的逐步 re-creation 显示我的应用程序运行良好，直到我在我的应用程序中添加 Xamarin.Forms.Maps 包。我正在安装最新版本的 Maps 包，它正在将它的依赖包升级到更高版本。地图插件导致 Xamarin.Forms 包从 2.3.2.127 升级到 2.3.3.180。因此，当我在发布模式下使用此版本的 Xamarin Forms 部署应用程序时，它导致应用程序崩溃和我之前在上面的回复中提到的 UI 问题。
为了解决这个问题，我回到了与 2.3.2.127 版本的 Xamarin Forms 兼容的情人版地图，瞧！
Xamarin Forms 2.3.3.180 版本似乎存在错误。
我们开发了支持 Android、iOS 和 Windows Phone 的 Xamarin Forms 应用程序。在调试模式下部署时，该应用程序可在所有三个操作系统上运行。
在发布模式下部署时，它还在 Android 和 iOS 上工作。当使用 Release 模式部署时，在 Windows Phone 8.1/10 上显示启动画面后立即崩溃，但奇怪的是，当使用 Debug 模式部署时一切正常。

我在这个问题上取得了一些进展。 FontFamily 属性 在我的案例中引起了问题。因此，如果在 Release 模式下删除 fontfamily 属性 和 运行 应用程序，则不再抛出异常，但屏幕在设备上的呈现方式与在 Debug 中呈现的方式完全不同模式。
我附上了两个屏幕截图。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，我有以下问题：
- 为什么应用程序在调试模式下正常工作而不是在发布模式下 模式？
- 为什么屏幕在调试模式下正确呈现而不是 发布模式？
- 为什么它不像它抛出的那样抛出任何错误 释放模式？
- 是否有遗漏的参考资料？不确定是否属于这种情况，因为应用程序会抛出异常说明。
有什么建议吗？
几个简短的笔记：
1.- 看起来“注册”按钮占用了所有屏幕高度，您是否尝试过为此按钮指定高度？类似于：
Button.HeightRequest = "40";
2.- 您是否尝试过链接行为 "Don't link"？
我的问题终于解决了。如果您遇到同样的问题，请在下面找到解决方案。
项目的逐步 re-creation 显示我的应用程序运行良好，直到我在我的应用程序中添加 Xamarin.Forms.Maps 包。我正在安装最新版本的 Maps 包，它正在将它的依赖包升级到更高版本。地图插件导致 Xamarin.Forms 包从 2.3.2.127 升级到 2.3.3.180。因此，当我在发布模式下使用此版本的 Xamarin Forms 部署应用程序时，它导致应用程序崩溃和我之前在上面的回复中提到的 UI 问题。
为了解决这个问题，我回到了与 2.3.2.127 版本的 Xamarin Forms 兼容的情人版地图，瞧！
Xamarin Forms 2.3.3.180 版本似乎存在错误。
