How to Publish a ClickOnce application with Azure DevOps Pipeline on different environments?

Question

I try for several days now to publish my ClickOnce application with Azure DevOps Pipeline. Before going in detail here is what I would like to do from my release view:

I started with one artifact and 2 release stage modifying the config.deploy file with staging variables during my Staging stage and modifying the config.deploy file with production variables during my Production stage. Deployment was working fine but installation of application was not working because of hash check system.

So I decided to create 2 builds with 2 artifacts. I renamed the classic drop by a drop_staging during my first build and drop_production for my second build. I was hoping the build system (MSBuild) was able to select the correct app.Debug.config then app.Release.config file during the build and publish process.

Here is my build definition

Here is my build arguments

/target:publish 
/p:ApplicationVersion=$(Build.BuildNumber) 
/p:PublishURL=http://app-staging.example.com/   
/p:UpdateEnabled=true  
/p:UpdateMode=Foreground  
/p:ProductName="App Staging" 
/p:OutputPath="$(build.ArtifactStagingDirectory)\Publish\\"

Configuration is set to Staging for first build then on Production for second build. I have, of course, a Staging and Production build definition in visual Studio. I have an app.config with app.Staging.config and app.Production.config in my project.

I cannot simply add a task to transform my config file after the build because I will not respect the hash. I should find a way to say to my build to use the correct XML transformation config file. I don't see any other solution or maybe applying this transformation before the build? Is it possible? What are your solutions?

Answer 1

finally I could solve this by adding a file transform before my build.

In case you need more help here is my YAML detail for transformation

steps:

- task: FileTransform@1

  displayName: 'File Transform: '

  inputs:

    folderPath: App.Example

    enableXmlTransform: true

    xmlTransformationRules: '-transform **\*.Staging.config -xml **\*.config'

    fileType: xml

#Your build pipeline references the ‘BuildPlatform’ variable, which you’ve selected to be settable at queue time. Create or edit the build pipeline for this YAML file, define the variable on the Variables tab, and then select the option to make it settable at queue time. See https://go.microsoft.com/fwlink/?linkid=865971



steps:

- task: VSBuild@1

  displayName: 'Build solution'

  inputs:

    solution: Example.sln

    msbuildArgs: '/target:publish /p:ApplicationVersion=$(Build.BuildNumber) /p:PublishURL=http://staging.example.com/   /p:UpdateEnabled=true  /p:UpdateMode=Foreground  /p:ProductName="App Staging" /p:OutputPath="$(build.ArtifactStagingDirectory)\Publish\\"'

    platform: '$(BuildPlatform)'

    configuration: Staging
