ClickOnce发布具有更新证书的新版本 [英] ClickOnce publish new version with updated certificate

问题描述

我有一个使用ClickOnce分发的应用程序.我用从Thawte购买的证书签名，并发布了该应用程序的多个版本.证书现已过期，我需要发布另一个带有程序修复的版本.我有一个更新的证书，但是用它发布了一个新版本后，我的应用程序尝试更新时出现错误.我不使用ClickOnce自动更新，而是使用代码检查并执行更新.

我在这个问题上搜索了一些帮助，并找到了一些论坛，说我很不走运，没有解决办法……但是它们似乎有点老了，我当时希望在VS 2008中可能已解决此问题.有谁知道如何解决这个问题?

我最终遇到的错误是对象引用未设置为对象的实例".当我尝试在代码中执行.CheckForDetailedUpdate时，我使用它来更新我的应用程序:

I have an application that is distributed using ClickOnce. I sign it with a certificate purchased from Thawte and have published several versions of the application. The certificate has now expired and I need to publish another version with a program fix. I have a renewed certificate but after publishing a new version with it I get an error when my application tries to update. I do not use ClickOnce automatic updates but instead check for and perform the updates in code.

I''ve searched a bit for some help on this matter and have found a few forums that say I''m just out of luck and there isn''t a fix...but they seem to be kind of old and I was hoping that with VS 2008 perhaps this has been fixed. Does anyone know how to get around this issue?

The error that I end up with is "Object reference not set to an instance of an object." When I try to perform the .CheckForDetailedUpdate in the code I use to update my app:

       Dim updateInfo As System.Deployment.Application.UpdateCheckInfo = Nothing
       ''Check if application is network deployed
       If System.Deployment.Application.ApplicationDeployment.IsNetworkDeployed Then
           ''Application is network deployed
           Dim objAppDeploy As System.Deployment.Application.ApplicationDeployment = System.Deployment.Application.ApplicationDeployment.CurrentDeployment
           ''Check for updates and get update information
           Try
               updateInfo = objAppDeploy.CheckForDetailedUpdate()
           Catch ex As System.Deployment.Application.DeploymentDownloadException
               Return "Program updates for " & gblstrFormText & " cannot be downloaded at this time." & _
                      vbCrLf & "Please check your network connection and try again." & _
                      " If the problem persists, please contact support." & _
                      vbCrLf & vbCrLf & "Error: " & _
                      ex.Message
           Catch ex As InvalidOperationException
               Return "This program cannot be updated. It is likely not a ClickOnce application." & _
                      vbCrLf & vbCrLf & "Error: " & ex.Message
           Catch ex As Exception
              '' ***** THIS IS THE EXCEPTION THAT GETS HIT *******
               Return "This program cannot be updated. " & _
                      vbCrLf & vbCrLf & "Error: " &

''...rest of the code is not relevant
