UWP App无法启动 [英] UWP App Won't Start

问题描述

我有一个UWP应用.我正在使用Visual Studio 2017 15.4.1. UWP应用程序是一种商店应用程序，已部署到Microsoft Store.我的应用程序在商店中运行良好，并且在Visual Studio中播放时也运行良好.然后最近发生了一个孤立的存储问题，因此我进入应用程序和功能"中的应用程序，然后单击高级选项->重置.不知何故，这炸毁了我在计算机上安装的应用.我们的应用程序不再显示为已安装的应用程序，当我尝试从商店中安装该应用程序时，出现错误，代码为0x80073CF9.因此，我无法卸载或在计算机上重新安装.我试过运行sfc/scannow等，以找出问题所在，但似乎无济于事.

I have a UWP app. I'm using Visual Studio 2017 15.4.1. The UWP app is a store app and has been deployed to the Microsoft Store. My app was working fine in the store, and it was also working fine when I hit play in Visual Studio. Then recently, an isolated storage issue started occurring so I went in to the app in "Apps & Features" and hit Advanced Options -> Reset. Somehow this has fried my app installation on my machine. Our app no longer shows up as an installed app, and when I try to install the app from the store, I get an error with a code of 0x80073CF9. So, I can't uninstall, or reinstall on my machine. I've tried running sfc /scannow etc. to find out what's wrong, but nothing seems to help.

这甚至不会让我担心太多，但是我现在甚至无法开发，因为当我尝试从Visual Studio运行应用程序时，会出现以下错误:

This wouldn't even worry me too much, but I can't even develop right now because when I try to run the app from Visual Studio, I get this error:

为了调试该项目，必须从Windows使用它 商店应用程序项目，该项目创建一个包并标记为启动" 项目

In order to debug this project, you must consume it from a Windows Store app project that creates a package and is marked as the Startup Project

我在构建的输出窗口中收到此错误

I'm getting this error in the output window from the build

4> DEP0700:应用程序注册失败. [0x80073CF9]另一个用户 已经安装了此应用程序的未打包版本.目前 用户不能用打包的版本替换它.冲突的 程序包是[APP NAME]，它已发布 由CN = [Publisher].

4>DEP0700: Registration of the app failed. [0x80073CF9] Another user has already installed an unpackaged version of this app. The current user cannot replace this with a packaged version. The conflicting package is [APP NAME] and it was published by CN=[Publisher].

我做错了什么?

推荐答案

您可以使用Get-appxpackage -allusers *<appname>* | Remove-AppxPackage

所有用户 选项在这里很重要.

The allusers option is important here.

您还可以尝试在 C:\ Users \\ AppData \ Local \ Packages \ 中手动删除应用程序缓存文件夹的内容.如果此处有一个锁定文件，则整个部署将失败.

You can also try to manually remove the content of the application cache folder in C:\Users\\AppData\Local\Packages\. If you have one locked file here, the whole deployment will fail.
