Type: Bug

Enter Task Name: NuGetToolInstallerV1

Environment

Azure Pipeline - Microsoft-hosted agent Running on the windows pool windows-2019

Issue Description

Trying to install the nuget preview with NuGetToolInstallerV1 to workaround an issue with nuget and the credentials manager (https://github.com/microsoft/artifacts-credprovider/issues/91)

Task definition

- task: NuGetToolInstaller@1
      inputs:
        versionSpec: '5.5.0-preview1'

This was tried with and without the checkLatest flag.

According to the docs here here it should find available version listed in this json file but it seems it cannot find it.

Hi! As far as I know this is still an issue and has not been resolved. Using PowerShell doesn’t seem like it should be “the solution” to people having to wait for NUGET versions to get out of preview? This is still happening with NUGET 6.0 on the azure cloud, and we’ve had to revert to .NET 5.0 because we’re getting errors thrown trying to use the preview.

It would be nice to have a “toggle preview” option, just like how the .net installer has “includePreviewVersions: true”, which would alleviate this problem.
