SonarScanner for .NET 10

An optimized, CI-ready Docker image with SonarScanner for .NET preinstalled, built on the official .NET 10 SDK (GA) base image.

This image is designed for static code analysis of .NET projects using SonarQube or SonarCloud in CI/CD pipelines.

---

🎯 Purpose

This image exists to provide a consistent, fast, and reproducible Sonar analysis environment across multiple repositories and CI systems.

Instead of installing .NET SDK and SonarScanner on every pipeline run, teams can reuse this image as a golden CI utility image.

---

🔧 What's Included

• .NET SDK 10.0 (GA, stable)
• SonarScanner for .NET (dotnet-sonarscanner)
• Official Microsoft Ubuntu-based image
• Multi-architecture support

⚠️ This image is intended only for CI/static analysis, not for production runtimes.
