This documentation shows the tutorial on how to integrate Visual Studio Code Analysis and Code Metrics in Azure Pipelines using YAML. Follow the steps:

1. Open Visual Studio 2019 and open project or solution and select your project.
2. Now you have to add a NuGet package named “Microsoft.CodeAnalysis.Metrics” to your solution. For this right click on the solution in Solution Explorer and click on Manage NuGet Packages for Solution.

3. Browse for Microsoft.CodeAnalysis.Metrics in the search bar. Click on the package. Select all your projects in the solution and click on Install.

4. In the next 2 windows click on OK then Accept. Wait until the package gets added to all your projects.

5. Now save all your changes. Then in team explorer commit your changes with a commit message.

6.  Sync the changes with the server in Azure Repos.

7. Navigate to your project in Azure DevOps and go to Build section of Pipelines.

8. Click on New Pipeline to setup a pipeline in YAML. If you have a n existing YAML pipeline you can add the stage to it.

9. Click on Azure Repos Git and then select your repository.

10. Click on Starter Pipeline for a new pipeline.

11. Add the following stage to your existing pipeline for Code Analysis and Code Metrics .

 - stage: CodeScan
   dependsOn: []
   jobs:
     - job: CodeScan
       pool:
        vmImage: 'vs2017-win2016'
       steps:
       - task: NuGetCommand@2
	   displayName: NuGetRestore
         inputs:
           restoreSolution: '$(solution)'
       - task: VSBuild@1
         displayName: CodeAnalysis
         inputs:
           solution: '$(solution)'
           msbuildArgs: '/p:RunCodeAnalysis=true'
           platform: '$(buildPlatform)'
           configuration: '$(buildConfiguration)'
       - task: VSBuild@1
         displayName: CodeMetrics
         inputs:
           solution: '$(solution)'
           msbuildArgs: '/t:Metrics /p:MetricsOutputFile=$(Build.ArtifactStagingDirectory)/PartsUnlimitted.Metrics.xml' # Modify xml file name according to project
           platform: '$(buildPlatform)'
           configuration: '$(buildConfiguration)'
       - task: PublishBuildArtifacts@1
         displayName: 'Publish Metrics'
         inputs:
           PathtoPublish: '$(Build.ArtifactStagingDirectory)'
           ArtifactName: 'MetricsReport'
           publishLocation: 'Container'

Note: Add solution, buildPlatform and buildConfiguration in the variables section of the pipeline.

variables:
  solution: '**/*.sln' # Provide path of .sln file here
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

12. Add other stages and dependencies for build, deploy or any other functionality according to the needs of the project. If you only want the pipeline for Code Metrics and Code Analysis, you can go for the single stage complete script provided below. Remove everything in your Starter Pipeline and add the following script. 

trigger:
  - master
  
  variables:
    solution: '**/*.sln' # Provide path of .sln file here
    buildPlatform: 'Any CPU'
    buildConfiguration: 'Release'
  
  pool:
    vmImage: 'vs2017-win2016'
  
  steps:
  - task: NuGetCommand@2
    displayName: NuGetRestore
    inputs:
      restoreSolution: '$(solution)'
  - task: VSBuild@1
    displayName: CodeAnalysis
    inputs:
      solution: '$(solution)'
      msbuildArgs: '/p:RunCodeAnalysis=true'
      platform: '$(buildPlatform)'
      configuration: '$(buildConfiguration)'
  - task: VSBuild@1
    displayName: CodeMetrics
    inputs:
      solution: '$(solution)'
      msbuildArgs: '/t:Metrics /p:MetricsOutputFile=$(Build.ArtifactStagingDirectory)/PartsUnlimitted.Metrics.xml'
      platform: '$(buildPlatform)'
      configuration: '$(buildConfiguration)'
  - task: PublishBuildArtifacts@1
    displayName: 'Publish Metrics'
    inputs:
      PathtoPublish: '$(Build.ArtifactStagingDirectory)'
      ArtifactName: 'MetricsReport'
      publishLocation: 'Container'

13. Click on Save and run to run the pipeline.

14. Enter a commit message and click Save and run.

15. View the live logs of the pipeline to see Code Analysis. You can also download the logs if required.

16. The Code Metrics report will be published as an XML file inside the Artifact generated after the pipeline. For this navigate to the Runs tab of your pipeline, click on any Run you want.

17. You can find the report by clicking Artifacts button.

18. Download the XML file to view the Code Metrics report.

19. Congrats!!!!! You are Done.
