Nuget restore not working with artifact feed in Azure Devops

Question

NuGet restore fails 404 from feed on another project in same organization.

When using nuget restore from a pipeline the feed inside a different project is not found.

Answer 1

After searching for a long time, these are the steps necessary to make it work consistently:

Setup permissions

• Make sure to add Build Service of the consuming project to the permissions of the feed
• Make sure the consuming project has these two settings disabled
  • Project settings (bottom left) --> Pipelines --> Settings
    • Limit job authorization scope to current project for non-release pipelines
    • Limit job authorization scope to current project for release pipelines

Setup build pipeline

• Use the .Net Core CLI Task
• Ideally you would use a nuget.config file and make sure to check it in
• Set the feedsToUse to 'config'

azure-pipelines.yml

- task: DotNetCoreCLI@2
      displayName: DotNetCore-Restore
      inputs:
        command: 'restore'
        projects: '$(PathToSolution)'
        feedsToUse: 'config'
        nugetConfigPath: '$(PathToNugetConfig)/nuget.config'
        includeNuGetOrg: true

nuget.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <clear />
    <add key="feed_name" value="feed_url" />
  </packageSources>
</configuration>

There is no need to add an authenticate task to the pipeline as the dotnet command does this by itself... However:

Most dotnet commands, including build, publish, and test include an implicit restore step. This will fail against authenticated feeds, even if you ran a successful dotnet restore in an earlier step, because the earlier step will have cleaned up the credentials it used.
