🧠 What You’ll Learn

In this tutorial, you’ll learn how to:

Set up SonarQube locally or on a server

Integrate SonarScanner for .NET

Analyze code quality and security metrics

Identify code smells, bugs, and vulnerabilities

Generate a comprehensive dashboard report for your project

By the end, you’ll know how to keep your .NET projects clean, consistent, and maintainable — whether you’re a solo developer or part of a CI/CD pipeline.

⚙️ Prerequisites

Before you start, make sure you have:

.NET SDK installed (6.0 or later)

SonarQube (Developer or Community Edition)

PostgreSQL or any supported database

Basic understanding of build pipelines

🔧 Step 1: Install and Configure SonarQube

You can install SonarQube locally with PostgreSQL on Windows.
Follow this guide:

Once installed:

Start the SonarQube server (StartSonar.bat).

Log in at http://localhost:9000.

Create a new project and generate a token.

🔍 Step 2: Configure SonarScanner for .NET

Install the SonarScanner for .NET tool:

dotnet tool install --global dotnet-sonarscanner

Initialize the scanner in your project:

dotnet sonarscanner begin /k:"ProjectKey" /d:sonar.host.url="http://localhost:9000" /d:sonar.login="your_token"
dotnet build
dotnet sonarscanner end /d:sonar.login="your_token"

🧪 Step 3: Run the Scan and Analyze Results

Once the scan completes, open your SonarQube dashboard.

Navigate to Issues → Security Hotspots → Code Smells.

Review and fix the highlighted issues directly in your code editor.

📊 Step 4: Continuous Integration (Optional)

You can integrate SonarQube analysis into your CI/CD pipelines:

Jenkins: Add SonarQube plugin and call the same scanner steps.

Azure DevOps: Use the “Prepare Analysis on SonarQube” task.

GitHub Actions: Use SonarSource/sonarcloud-github-action.

This ensures that every code commit is automatically scanned for quality and compliance.

💡 Why Use SonarQube?

✅ Detect vulnerabilities early
✅ Improve team-wide code consistency
✅ Enforce quality gates before merging
✅ Build confidence in every release

🧱 Ideal For

.NET Developers aiming to improve code health

DevOps Engineers integrating static code analysis

Teams adopting DevSecOps practices
