Change config and sign a click once deployment for test in an Azure build application:

I have the following release pipeline in Azure:

Continuous Integration pipeline that will build for every check in on master branch. This build will trigger a Continuous Delivery pipeline that will deploy the release for the click once application to test. The same installation wil be deployed to production after approval in test on this pipeline.

I want the same build that I tested to go to production. The click once is compiled for release. The app.config I have in source is the production version. So once installed the app will default be configured to connect to production datasources.

For test however I want the app.config to be replaced with a app.config.debug version. This is a app.config that contains the test and debug datasources.

After putting this config file in the deployment the signature for the click once is no longer valid. I resigned the click once manifest for the changed config with a tool from Microsoft .NET SDK.

I used the mage.exe (from .NET framework Tools). Path for my installation: C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.7.2 Tools\mage.exe.

I added 3 files to the source directory:

mage.exe
app.config.debug
ACertificateFile.pfx. This pfx is the same I used in the project to sign the manifest file.

After adding these 3 files to the source folder I added a copy step in the build pipeline to add these files to the app.publish folder:

And a script to update the app.config and resign the manifest has to be executed before copying the files to the local deployment server.

@echo on
for /f “delims=” %%F in (‘dir “$(system.defaultworkingdirectory)_Bla.WPF.BLA-.NET Desktop-CI\$(System.TeamProject)-$(Build.BuildNumber)\Application Files” /B /AD’) do set deployDir=%%F
set “to=$(system.defaultworkingdirectory)_Bla.WPF.BLA-.NET Desktop-CI\$(System.TeamProject)-$(Build.BuildNumber)\Application Files\%DeployDir%”
set “from=$(system.defaultworkingdirectory)_Bla.WPF.BLA-.NET Desktop-CI\$(System.TeamProject)-$(Build.BuildNumber)”

copy /Y “%from%\App.config.debug” “%to%\BLA.exe.config.deploy”

ren “%to%*.deploy” *.
“%from%\mage” -sign “%to%\BLA.exe.manifest” -CertFile “%from%\ACertificateFile.pfx”
“%from%\mage” -update “%to%\BLA.exe.manifest” -CertFile “%from%\ACertificateFile.pfx”
“%from%\mage” -update “%from%\BLA.application” -appmanifest “%to%\BLA.exe.manifest” -CertFile “%from%\ACertificateFile.pfx”

ren “%to%*.*” *.*.deploy
ren “%to%*.manifest.deploy” *.
del “%from%\mage.exe”
del “%from%\App.config.debug”
del “%from%\ACertificateFile.pfx”
