Error Installing and Saving Semver Prerelease Modules with UpperCase PreRelease Labels from Azure Package Repositories

[adrian-andersson]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

1. Create an Azure DevOps Package Feed
2. Upload a module with a Semver Pre-release Version Tag with Uppercase letters (Such as 1.0.1-PREv001)
3. Register the repository using register-psresourcerepository and SPECIFICALLY the V3 feed
4. Try and download your module with either save-psresource or install-psresource
5. Encounter error -> Save-PSResource: Package with name 'AzureDevopsTest' and version '1.0.1-PREv001' could not be found in repository 'AzureTestRepo'

OBSERVATIONS:

• Everything works ok if I use a V2 feed in Azure DevOps
  • Since this document: private-powershell-library on microsoft Learn website has a specific note to use V3, this is not a desired outcome.
• Using github packages also works without an issue
• Using a non pre-release module works without issue (E.g. version 1.0.1) in Azure Packages.
• Using a prerelease tag that is all LOWERCASE (E.g. version 1.0.2-prev001) works without issue in Azure packages

HYPOTHESIS:

I suspect that the issue may be related to case sensitivity in the version string handling, particularly in the IsLatestVersionFirstForInstall() method. The packageContent URL in the metadata response has the version in lowercase (1.0.1-prev007), while the actual version string retains its original casing (1.0.1-PREv007). This inconsistency might be causing the method to fail in reconciling the version strings.

The issue does not occur with GitHub Packages, as the packageContent URL retains the casing of the version string.

Worth noting that invoking the rest API directly against Azure package feeds DOES NOT care about the casing at all, implying this is a problem with PSResourceGet when it is doing some version check.

Expected behavior

#Nuget V3 Feeds from Github Packages DO NOT exhibit this error

Could be that all that's needed is to add a ToLower() here?

Attached is a build of PSResourceGet with that change, can you check if it solves it?

Also seeing this behaviour, Find-PSresource can find the pre-release packages, however they can not be installed. Weird behaviour I noticed, if I pass it the prelease tag in all lowercase, the error message comes back with the correct casing of the tag of package installed in the feed, however still indicating it could not be found...

Hi @AlexandraDorey , mine is working when I use all lowercase, so that's what I've been doing and have updated my own code until this is rectified... I.e. this works: v2.0.0-prev001
