Meziantou.Analyzer

Meziantou.Analyzer is a powerful C# Roslyn analyzer that uses static analysis to detect bugs, surface security issues, and enforce best practices. It helps you catch real-world problems early—before they reach production—by analyzing your code as you write it and providing automated fixes when possible. Designed for both human developers and AI-assisted workflows, it acts as a safety net to keep your code reliable, consistent, and maintainable.
