Question

我已经开发UWP应用已有一段时间了。完全没有问题。将其连接到git repo和所有内容。因此，此解决方案和项目在3天前运行正常。我完成了一天的工作，提交了回购协议并关闭了计算机。当我今天回来时，尝试在Visual Studio 2019中启动我的UWP以在本地计算机上开始调试时，我收到以下消息：

目标进程退出而没有引发CoreCLR启动事件。确保将目标进程配置为使用.NET Core。如果目标进程未在.NET Core上运行，则可能会出现这种情况。程序“ [2812] LaserMeasurementTool.exe”已退出，代码为-1073741701（0xc000007b）。 Windows Store应用程序“ 062a9632-d22f-4d48-991a-d1d51afe77e5_ebvsp9khn4a7w！App”的激活失败，错误为“应用程序未启动”。

有时在0xc000007b错误代码之后，它显示“找不到dll”，但并非每次都显示。

到目前为止，我已经尝试过：

清洁并重建解决方案
修复Visual Studio

我看到很多人都有这个问题。但是没有建议的解决方案对我有用。想知道是否还有更多我可以解决这个问题。如果无法运行我的程序来测试它，我做不到很多。

非常感谢您！

更新

自从第一篇文章开始，我已经尝试了其他一些方法：我已将VS 2019中的调试器更改为仅本机。这提示了一个不同的错误对话框

此后，通过单击“帮助”将我带到this site

此页面可让我打开事件查看器以获取有关该问题的更多详细信息，这是事件查看器给我的：

激活062a9632-d22f-4d48-991a-d1d51afe77e5_ebvsp9khn4a7w！应用失败。错误代码：该应用未启动。.激活阶段：COM ActivateExtension

最后，此时VS 2019中的输出窗口显示如下：

'LaserMeasurementTool.exe'（Win32）：已加载'\ lav-dc1 \ Folder Redirection \ bwhelan \ Documents \ Source \ Repos \ 132 Laser Measurement Tool \ LaserMeasurementTool \ LaserMeasurementToolUWP \ bin \ x86 \ Debug \ AppX \ LaserMeasurementTool.exe '。 'LaserMeasurementTool.exe'（Win32）：已加载'C：\ WINDOWS \ System32 \ ntdll.dll'。符号已加载。 'LaserMeasurementTool.exe'（Win32）：已加载'C：\ WINDOWS \ System32 \ kernel32.dll'。符号已加载。 'LaserMeasurementTool.exe'（Win32）：已加载'C：\ WINDOWS \ System32 \ KernelBase.dll'。符号已加载。 'LaserMeasurementTool.exe'（Win32）：已加载'C：\ WINDOWS \ System32 \ ucrtbase.dll'。符号已加载。 'LaserMeasurementTool.exe'（Win32）：已加载'C：\ Program Files \ WindowsApps \ Microsoft.NET.CoreRuntime.2.2_2.2.27902.3_x86__8wekyb3d8bbwe \ uwphost.dll'。 'LaserMeasurementTool.exe'（Win32）：已卸载'C：\ Program Files \ WindowsApps \ Microsoft.NET.CoreRuntime.2.2_2.2.27902.3_x86__8wekyb3d8bbwe \ uwphost.dll' 线程0x3b30已退出，代码为-1073741701（0xc000007b）。线程0x1208已退出，代码为-1073741701（0xc000007b）。程序“ [15228] LaserMeasurementTool.exe”已退出，代码为-1073741701（0xc000007b）。

总体而言，它仍然无法正常工作，我想我会添加这些东西，这些东西我现在已经尝试过，但由于我的情况而失败了。

Answer 1

我以前见过这个问题，有点难以捉摸。尝试关闭Visual Studio并删除文件夹中的bin和obj文件夹。这应该确保没有残留物（有时使用Clean Solution是不够的）。然后通过“开始”菜单从PC上卸载应用程序的已安装版本，以便从全新状态进行安装。

如果这无济于事，我发现有几个报告说项目文件夹中有无效的App.config文件时发生了此问题。检查是否没有App.config文件，如果是，请尝试将其删除。

如果这两种方法均失败，也请尝试将项目克隆到其他位置，然后重试。确保项目路径不要太长（此问题在今天并不那么严重，但仍然确实发生，由于bin文件路径是太深）。

对于UWP应用，该程序已退出，代码为-1073741701（0xc000007b）
