单击一次部署：下载 XXX.manifest 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，从应用程序服务器（从 URL 应用程序已发布到）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部署（不再存在，因为它已被新部署取代）。 "funny" 的事情是我们从不同的机器和位置安装了这个版本，它对除了两个人 "behind that proxy" 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，所以我暂时不提它们。

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清单的代理的问题。

此外，卸载应用程序（从控制面板）并删除 ClickOnce 文件缓存（%userprofile%\AppData\Local\Apps.0*.*），如下所述 link 有助于修复过去也有很多问题：https://support.microsoft.com/en-us/kb/2713442

希望有一天这能对某人有所帮助...
