# .NET project

Before you begin, read the [Azure Pipelines integration overview](/sonarqube-server/2025.5/devops-platform-integration/azure-devops-integration/azure-pipelines-integration-overview.md) page.

Once you have created your project in SonarQube Server and set up feature integration for your project, 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 editor.

{% hint style="info" %}

* The use of the Classic editor 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 the [Using various features](/sonarqube-server/2025.5/devops-platform-integration/azure-devops-integration/adding-analysis-to-pipeline/various-features.md) page.

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

Analysis parameters can be set at different levels, see the [Creating and configuring your project](/sonarqube-server/2025.5/devops-platform-integration/azure-devops-integration/creating-your-project.md#configuring-analysis-parameters) article. 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 task inputs, see the [/pages/iYuxIs21mGMTe19j9qao#task-inputs-specific-to-the-.net-mode](https://docs.sonarsource.com/sonarqube-server/2025.5/devops-platform-integration/azure-devops-integration/adding-analysis-to-pipeline/pages/iYuxIs21mGMTe19j9qao#task-inputs-specific-to-the-.net-mode "mention") article. 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. Also, see the [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/2025.5/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/2025.5/analyzing-source-code/scanners/sonarqube-extension-for-azure-devops.md) you’re using.

```yaml

 # Checkout the repository 
- checkout: self

 # Disable shallow fetch

# Prepare Analysis Configuration task
- task: SonarQubePrepare@8

    scannerMode: 'dotnet'
    projectKey: '<YourProjectKey>'

# Dotnet build task

# Run Code Analysis task
- task: SonarQubeAnalyze@8

# Publish Quality Gate Result task
- task: SonarQubePublish@8
  inputs:
    pollingTimeoutSec: '300'
```

</details>

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

To add the analysis to your classic build pipeline:

1. In the Azure DevOps Classic 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 service connection you created during setup. See the [Setting up project integration](/sonarqube-server/2025.5/devops-platform-integration/azure-devops-integration/setting-up-project-integration.md) page for more information about adding a connection.
   * Under **Choose a way to run the analysis**, select **Integrate with .NET**.
   * 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.

## Configuring your scanner

If you're using the .NET scanner to complete the analysis, see the [Configuring the scanner](/sonarqube-server/2025.5/analyzing-source-code/scanners/dotnet/configuring.md) for NET page for language-specific details.

There's also an article about running [Configuring the scanner](/sonarqube-server/2025.5/analyzing-source-code/scanners/dotnet/configuring.md#multi-language-analysis) for select languages when the `sonar.scanner.scanAll` parameter is enabled via the `extraProperties` listed in your [SonarQube tasks for Azure Pipelines](/sonarqube-server/2025.5/devops-platform-integration/azure-devops-integration/adding-analysis-to-pipeline/sonarqube-tasks.md#prepare-analysis-configuration).
