Azure Pipeline Nuget Package Versioning Scheme, How to Get "1.0.$(Rev:r)"

Working YAML example for Packaging/Versioning using byBuildNumber

NOTE the second parameter of the counter - it is a seed value, really useful when migrating builds from other build systems like TeamCity; It allows you to set the next build version explicitly upon migration. After the migration and initial build in Azure DevOps, the seed value can be set back to zero or whatever start value (like 100) you may prefer every time majorMinorVersion is changed:

reference: counter expression

name: $(majorMinorVersion).$(semanticVersion) # $(rev:r) # NOTE: rev resets when the default retention period expires

pool: 
  vmImage: 'vs2017-win2016' 

# pipeline variables
variables:
  majorMinorVersion: 1.0
  # semanticVersion counter is automatically incremented by one in each execution of pipeline
  # second parameter is seed value to reset to every time the referenced majorMinorVersion is changed
  semanticVersion: $[counter(variables['majorMinorVersion'], 0)]
  projectName: 'MyProjectName'
  buildConfiguration: 'Release'

# Only run against master
trigger:
- master

# Build
- task: DotNetCoreCLI@2
  displayName: Build
  inputs:
    projects: '**/*.csproj'
    arguments: '--configuration $(BuildConfiguration)'

# Package
- task: DotNetCoreCLI@2
  displayName: 'NuGet pack'
  inputs:
    command: 'pack'
    configuration: $(BuildConfiguration)
    packagesToPack: '**/$(ProjectName)*.csproj'
    packDirectory: '$(build.artifactStagingDirectory)'
    versioningScheme: byBuildNumber # https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/build/dotnet-core-cli?view=azure-devops#yaml-snippet

# Publish
- task: DotNetCoreCLI@2
  displayName: 'Publish'
  inputs:
    command: 'push'
    nuGetFeedType: 'internal'
    packagesToPush: '$(build.artifactStagingDirectory)/$(ProjectName)*.nupkg'
    publishVstsFeed: 'MyPackageFeedName'

byBuildNumber uses the build number you define in your YAML with the name field.

Ex: name: $(Build.DefinitionName)-$(date:yyyyMMdd)$(rev:.r)

So if you set your build format to name: 1.0.$(rev:.r), it should work as you expect.

Azure Pipeline Nuget Package Versioning Scheme, How to Get “1.0.$(Rev:r)”

This should be a issue in the documentation. I reproduced this issue when I set $(Major).$(Minor).$(rev:.r) in the Build number format in the Options of build pipeline:

However, I suddenly noticed that the build number is not correct with that format after many build tests:

There are two points . between 0 and 2 (Open above image in a new tab). Obviously this is very strange. So, I changed the Build number format to:

$(Major).$(Minor)$(rev:.r)

Or

$(Major).$(Minor).$(rev:r)

Now, everything is working fine.

As test, I just set the Build number format to $(rev:.r), and the build number is .x. So, we could confirm that the value of $(rev:.r) including the . by default.

Note: Since where Major and Minor are two variables defined in the build pipeline, so we need defined them in the variables manually.

Hope this helps.
