prepare-release

name: prepare-release description: Prepares the repository for an internal release branch. Use this when asked to "prepare for a release", "prepare internal release branch", or similar release preparation tasks.

Prepare Internal Release Branch

When preparing a public branch for internal release, apply the following changes:

1. Directory.Build.props

Add NU1507 warning suppression after the TestNetCoreTargetFrameworks PropertyGroup. Internal branches don't use package source mapping due to internal feeds:

<!-- Internal branches don't use package source mapping feature due to internal feeds, so disable NU1507 warning saying it should be used. -->
<PropertyGroup>
  <NoWarn>$(NoWarn);NU1507</NoWarn>
</PropertyGroup>

Insert this new PropertyGroup right after the closing </PropertyGroup> that contains TestNetCoreTargetFrameworks.

2. NuGet.config

Remove the entire <packageSourceMapping> section. This section looks like:

<!-- Define mappings by adding package patterns beneath the target source.
     https://aka.ms/nuget-package-source-mapping  -->
<packageSourceMapping>
  <packageSource key="dotnet-public">
    <package pattern="*" />
  </packageSource>
  <packageSource key="dotnet-eng">
    <package pattern="*" />
  </packageSource>
  <!-- ... more packageSource entries ... -->
</packageSourceMapping>

Important: Do NOT add new internal feed sources to NuGet.config - those are managed by Dependency Flow automation and will be added automatically.

3. eng/Versions.props

Update these two properties (do NOT change any version numbers):

Change StabilizePackageVersion from false to true:

<StabilizePackageVersion Condition="'$(StabilizePackageVersion)' == ''">true</StabilizePackageVersion>

Change DotNetFinalVersionKind from empty to release:

<DotNetFinalVersionKind>release</DotNetFinalVersionKind>

4. eng/pipelines/templates/BuildAndTest.yml

Add Private Feeds Credentials Setup

After the Node.js setup task (the NodeTool@0 task), add these two tasks to authenticate with private Azure DevOps feeds:

  - task: PowerShell@2
    displayName: Setup Private Feeds Credentials
    condition: eq(variables['Agent.OS'], 'Windows_NT')
    inputs:
      filePath: $(Build.SourcesDirectory)/eng/common/SetupNugetSources.ps1
      arguments: -ConfigFile $(Build.SourcesDirectory)/NuGet.config -Password $Env:Token
    env:
      Token: $(dn-bot-dnceng-artifact-feeds-rw)

  - task: Bash@3
    displayName: Setup Private Feeds Credentials
    condition: ne(variables['Agent.OS'], 'Windows_NT')
    inputs:
      filePath: $(Build.SourcesDirectory)/eng/common/SetupNugetSources.sh
      arguments: $(Build.SourcesDirectory)/NuGet.config $Token
    env:
      Token: $(dn-bot-dnceng-artifact-feeds-rw)

Comment Out Integration Tests

Comment out the integration tests step as they require authentication to private feeds that isn't available during internal release builds:

  - ${{ if ne(parameters.skipTests, 'true') }}:
    # Skipping integration tests for now as they require authentication to the private feeds
    # - script: ${{ parameters.buildScript }}
    #           -integrationTest
    #           -configuration ${{ parameters.buildConfig }}
    #           -warnAsError 1
    #           /bl:${{ parameters.repoLogPath }}/integration_tests.binlog
    #           $(_OfficialBuildIdArgs)
    #   displayName: Run integration tests

5. azure-pipelines.yml

Remove the codecoverage stage entirely. This is the stage that:

• Has displayName: CodeCoverage
• Downloads code coverage reports from build jobs
• Merges and validates combined test coverage
• Contains a CodeCoverageReport job

Also remove the codecoverage dependency from the post-build validation's validateDependsOn list:

# Remove this conditional dependency block:
- ${{ if eq(parameters.runTests, true) }}:
  - codecoverage

Files NOT to modify

• eng/Version.Details.xml: Version updates are managed by Dependency Flow automation
• eng/Versions.props version numbers: Package versions are managed by Dependency Flow automation
• NuGet.config feed sources: Internal darc feeds are added automatically by Dependency Flow
