c# - 单击一次部署 : Downloading XXX. list 未成功。 (404) 未找到

Question

我们的一位客户在部署新版本(从版本 2 升级到版本 3)后更新他们的 ClickOnce 应用程序并遇到问题。

首先，当他运行应用程序时，它似乎没有检测到已部署新版本。后来，从应用服务器(从应用程序发布到的 URL)手动下载最新的 AssemblyName.application 文件后，他收到以下错误，出于某种原因，它似乎一直在寻找旧的部署(它不不再存在，因为它已被新的取代)。 “有趣”的是，我们从不同的机器和位置安装了这个版本，它对除了“代理背后”的两个人之外的每个人都运行良好。这是他们收到的错误消息:

有人知道可能发生了什么吗？我们有一些怀疑，但由于我不想限制您的回答，所以我现在不会提及它们。

在此先感谢您的帮助!!!

万一它可以帮助将来的任何人:它最终成为缓存旧版本应用程序部署 list 的代理的问题。

此外，按照以下链接中的说明卸载应用程序(从控制面板)并删除 ClickOnce 文件缓存 (%userprofile%\AppData\Local\Apps\2.0*.*) 有助于解决过去的许多问题还有:https://support.microsoft.com/en-us/kb/2713442

希望有一天这能对某人有所帮助...
