iis-7.5 - 为什么 Web 部署代理服务 (MsDepSvc) 因 FileNotFoundException 而崩溃？

Question

我正在尝试使用 Web Deploy V2 将 .NET 4 Web 应用程序部署到 Windows 2008R2 服务器。作为此部署的一部分，我们将一些批处理文件复制到目标机器。当我执行下面的命令时，Web 部署代理服务 (MsDepSvc) 停止并且 FileNotFoundException 记录到系统应用程序事件日志中。

网络部署命令:

"C:\Program Files (x86)\IIS\Microsoft Web Deploy V2\msdeploy.exe" -verb:sync -source:contentPath="C:\work\27f84e3eca3a33d5\Output\BatchFiles" -dest:contentPath="c:_DeployCommands",computerName="192.168.1.14"

完整的控制台输出:

C:\Windows\system32>"C:\Program Files (x86)\IIS\Microsoft Web Deploy V2\msdepl y.exe" -verb:sync -source:contentPath="C:\work\27f84e3eca3a 3d5\Output\BatchFiles" -dest:contentPath="c:_DeployCommands",computer ame="192.168.1.14" Info: Using ID '326b55b4-602c-4cdf-ae5c-052e9d44b377' for connections to the remote server.

事件日志条目:

Application: MsDepSvc.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

我该如何诊断？

我们遇到了类似的问题。最好的办法是使用 ILSpy 反编译并在每个 catch block 中添加额外的日志记录并替换客户端上的 exe 以查看确切的错误。在我们的场景中，我们使用了可以工作的旧版本 7.1.1631.0。有一个较新的版本 7.1.1762.0 导致了这个问题。 exe 是从客户端而不是服务器复制的。
