Publish-PSResource does currently not work with Azure Artifacts

Prerequisites

Steps to reproduce

I tried to use PowerShellGet 3.0.0-beta19 for publishing a module to a Azure DevOps Artifacts feed.

At first I tried to register the feed using the v2 endpoint. But I have seen that the cmdlet Publish-PSResource hardcoded adds /package to the URL, if it is a NuGet v2 endpoint, because the PowerShell gallery apparently uses this. But my Azure Artifacts feed does not have this and therefore the cmdlet fails with HTTP404. The v2 endpoint for Azure Artifacts looks like this: https://pkgs.dev.azure.com/<org>/<project>/_packaging/<feedname>/nuget/v2/

Then I tried to register the the PS Repository using the NuGet v3 endpoint. This however fails with this error message:

Publish-PSResource : Unable to load the service index for source https://pkgs.dev.azure.com/<org>/<project>/_packaging/<feedname>/nuget/v3/index.json.

Is there a preference which version I should use? Is this something that still needs implementing and is there a temporary workaround I can use in the meantime?

I am having a really hard time getting things to work with Azure Artifacts using PowerShellGet 2.x (older NuGet version, authentication, double repository registration) and therefore I’d prefer switchtig to PowerShellGet 3.x if possible.

Expected behavior

PowerShellGet should publish the package.

Actual behavior

Neither on the v2 nor on the v3 endpoint I seem to be able to publish the package.

Thanks @hemisphera for the investigation and the PR, we have a major refactor of this cmdlet about to go out (beta 20), so after that we can retest this and see if the issue is resolved

We recommend publishing to AzureArtifacts with a V3 protocol URI for your repository. It’s fixed now and -Credential with CredentialInfo value should work as of this next release.
