# .NET project

Before starting, read [Azure Pipelines integration overview](/sonarqube-server/2025.2/devops-platform-integration/azure-devops-integration/azure-pipelines-integration-overview.md).

Once you have [Creating and configuring your project](/sonarqube-server/2025.2/devops-platform-integration/azure-devops-integration/creating-your-project.md) and [Setting up project integration](/sonarqube-server/2025.2/devops-platform-integration/azure-devops-integration/setting-up-project-integration.md), you can add the SonarQube Server analysis to your Azure build pipeline.

To create your Azure build pipeline, you can use either YAML or the Azure Classic interface.

{% hint style="info" %}

* The use of the Classic interface is not always possible (e.g. if your code is stored on GitHub).
* If you use YAML, SonarSource can provide you with YAML templates or code examples.
  {% endhint %}

If you need to use a specific scanner version, see [Using various features](/sonarqube-server/2025.2/devops-platform-integration/azure-devops-integration/adding-analysis-to-pipeline/various-features.md).

## About the analysis parameter setup <a href="#analysis-parameters" id="analysis-parameters"></a>

Analysis parameters can be set at different levels: see **Configuring the project analysis parameters** in [Setting up project integration](/sonarqube-server/2025.2/devops-platform-integration/azure-devops-integration/setting-up-project-integration.md)**.** When creating your pipeline, you will have to enter the project key and you may also enter the project version and name (For more information about these task inputs, see the **.NET mode** in the [SonarQube tasks for Azure Pipelines](/sonarqube-server/2025.2/devops-platform-integration/azure-devops-integration/adding-analysis-to-pipeline/sonarqube-tasks.md).). You may define additional parameters in this task. In that case, these parameters have precedence over parameters defined at the project or global level.

## Using YAML <a href="#yaml-pipeline" id="yaml-pipeline"></a>

Add the following SonarQube tasks to your YAML pipeline:

1. Before your build task, add a Prepare Analysis Configuration task.
2. After your build task, add a Run Code Analysis task.
3. After the Run Code Analysis task, add a Publish Quality Gate Result task.

See the YAML file example below. See also our [YAML pipeline templates](https://github.com/SonarSource/sonar-scanner-azdo/tree/master/its/fixtures). For information about the SonarQube task inputs, see [SonarQube tasks for Azure Pipelines](/sonarqube-server/2025.2/devops-platform-integration/azure-devops-integration/adding-analysis-to-pipeline/sonarqube-tasks.md).

{% hint style="info" %}
Make sure the SonarQube task version used in your YAML file is the correct one.\
For example, in `SonarQubePrepare@7`, `7` should correspond to the version of the [Azure DevOps Extension](/sonarqube-server/2025.2/analyzing-source-code/scanners/sonarqube-extension-for-azure-devops.md) you’re using.

```

</details>

## Using the Classic interface <a href="#classic-pipeline" id="classic-pipeline"></a>

To add the analysis to your classic build pipeline:

1. In Azure DevOps Classic interface editor, create or update your build pipeline.
2. Add a **Prepare Analysis Configuration** task before your build task:
   * In **SonarQube Server Service Endpoint**, select the SonarQube Server service connection you created in **Adding the SonarQube service connection to your AzDO project** in [Setting up project integration](/sonarqube-server/2025.2/devops-platform-integration/azure-devops-integration/setting-up-project-integration.md).
   * Under **Choose a way to run the analysis**, select **Integrate with MSBuild**.
   * In the **Project key** field, enter your project key.
   * Optionally, enter the project name and version.
3. Add a new **Run Code Analysis** task after your build task.
4. Add a new **Publish quality gate Result** on your build pipeline summary.
5. Ensure that the pipeline runs automatically for all the branches you want:
   * Under the **Triggers** tab of your pipeline, select **Enable continuous integration** and select all the branches for which you want SonarQube Server analysis to run automatically.
6. Save your pipeline.
