由于似乎没有很好的解决方案，我实现了一个新的ClickOnce卸载程序。它可以通过命令行从.NET调用，也可以作为自定义操作集成到WiX安装项目中。

https://github.com/6wunderkinder/Wunder.ClickOnceUninstaller

我们在Wunderlist 2.1版本中使用了这一点，从ClickOnce切换到了Windows安装程序包。它集成到安装过程中，对用户完全透明。

我可以确认WMIC不适用于ClickOnce应用程序。它们只是没有在其中列出。。。

我想把这个放在这里，因为我已经研究了很长一段时间，无法找到一个完整的解决方案。

我对整个编程工作还很陌生，但我认为这可以为如何进行提供一些想法。

它基本上验证应用程序当前是否正在运行，如果是，它会杀死它。然后它检查注册表以找到卸载字符串，将其放入批处理文件中，然后等待进程结束。然后它执行Sendkeys以自动同意卸载。就是这样。

您可以尝试使用隐藏开始。

不能取消ClickOnce应用程序的卸载对话框。你可以写一个小.NET应用程序来卸载ClickOnce应用程序，并以编程方式点击对话框上的按钮，这样用户就不需要执行任何操作。这是你能做的最好的事情。
