UWP App FileLoadException WindowsRuntime仅在移动设备上发生

在将商店生成的捆绑包部署到我的Windows 10移动设备上后,我的应用程序出现问题。我还将此上传到应用商店审核小组,但他们经常看到崩溃。所以我创建了一个空白项目,试图找出问题所在。

空白应用程序只包含一个使用StorageFolder API尝试查找文件夹的功能。如果它不存在,那么它只会显示一条消息,表明它没有找到。我还用try / catch包围了这个函数,因为我相信这段代码是我问题的罪魁祸首。

以下是Github上的空白项目:https://github.com/cmakthat/MobileCrashTesting

以下是Visual Studio中生成的包:https://1drv.ms/f/s!Anec4-FVkNsbhdtfR82xskiDviPW6g

更具体地说,这里也是代码:

这是部署到我的Windows 10移动设备时的纲要:

  • 在Visual Studio上以调试模式部署:Works
  • 在Visual Studio上以发布模式部署:Works
  • 部署&#34; _Test&#34;捆绑:工作
  • 部署&#34; appxupload&#34;在其中捆绑:FileLoadException

我得到的FileLoadException如下图所示: FileLoadException image

所以现在我迷失了该做什么。由于此拦截器,我无法通过商店批准我的应用。我原来的项目几个星期前正在运作,但现在突然间我开始遇到这些崩溃事件并且我没有改变任何重大事件。有什么想法吗?

在其中部署“appxupload”包:FileLoadException

您无法直接将appxupload部署到移动设备中。因为appxupload文件不完整。您可以通过将appxupload文件后缀名称修改为zip来验证这一点并进行探索。它包含两个文件appxbundle文件和appxsym文件。

appxsym文件上传到商店时,将使用appxupload。它将在商店云编译后生成完整的appxbundle文件。完整文件等于您的案例中描述的 _Test 捆绑包。

enter image description here

因此,部署“appxupload”软件包并不是一个好习惯。
