ProGet as ClickOnce publish target?

[MaxCascone]

We're looking into using ProGet as a publish target for our ClickOnce applications. Is there an established pattern for doing this? Where would they best be pointed - a true Feed, or an Asset Directory?

I'm not so familiar with ClickOnce publish targets, but my understanding is that ClickOnce is deployed to an ordinary web-based file directory, like a site in IIS that has "file browsing" enabled or something?

IF so, then I think Asset Directory would work. That's kind of like that, and is meant for general files. Feeds require a special API to access.

Let us know how it goes.

The person building this seemed to be having some luck with the Assets, he needed to use the api endpoint exposed in the download link area. I'll follow up when i get more info.

We had a fantastic support call with Alex and Rich, and they pointed us at this: https://docs.microsoft.com/en-us/visualstudio/deployment/server-and-client-configuration-issues-in-clickonce-deployments?view=vs-2019#use-third-party-web-servers

we haven't tried anything yet, but if anyone else comes along here, maybe it'll help.

Just thought I'd drop in and describe where we ended up with this. It works for us, YMMV.

This is running in the context of a Jenkins deploy run, but the concepts should apply to most other use cases.

There are a lot of env vars floating around in all of this; i know it's not ideal, but it's really the easiest way to move values around in Jenkins without going crazy with OO classes that are really hard to get working in the Jenkins context. I have recently come up with a pattern to store more complex objects in env vars as json strings, and convert them when needed.

Happy to answer any questions from anyone interested in using this admittedly obscure functionality.

// this is called from vars/deploy.groovy when appropriate
clickOnceDeploy([clickAppName:env.clickOnceName, clickAppPath:env.clickOnceDir, targetEnv:targetMap.key])

// defined in vars/deploy.groovy
def clickOnceDeploy(HashMap clickParms) {
  // find the zip in the download folder
  String dlFolder         = "${WORKSPACE}/${env.packageDownloadDir}"
  String clickOncePackage = "${dlFolder}/${env.releasePath}/${clickParms.clickAppPath}.zip" 
  String targetEnv        = clickParms.targetEnv
  String zipFileName      = "${clickOncePackage.replace('.zip', '')}-${targetEnv}.zip"

  // extract the zip - select the target env folder
  unzip zipFile: clickOncePackage, glob: "${targetEnv}/**", quiet: true

  // zip that folder up, use powershell to get the dir included
  pwsh "Compress-Archive -Path ${targetEnv} -DestinationPath ${zipFileName} -Force"

  // publish it to proget asset dir
  HashMap publishParams = [assetDir:"${clickParms.clickAppName}", zipFilePath:zipFileName]
  addToInfoMessages("Publishing ClickOnce App: ${clickParms.clickAppName}/${targetEnv}")
  publish.publishProGetAssetFromZip(publishParams)

// defined in vars/publish.groovy

  // check for required params
  assert publishParams.assetDir != null
  assert publishParams.zipFilePath != null

  publishParams.get('progetBase', env.progetUrl)

  String assetUrl = "${publishParams.progetBase}/${progetAssetImportApi}"
