Have you ever returned to a .NET project only to find it cluttered with unused code—methods, variables, or even entire classes that serve no purpose anymore? If so, you're not alone. As projects grow and evolve, it's easy for dead code to accumulate, quietly bloating your codebase and making maintenance harder. That's why I built Roslyn Unused Code Remover—a lightweight CLI tool that automatically identifies and removes unused code from your C# projects using the Roslyn compiler platform. ✨ What It Does This tool leverages the power of Roslyn analyzers to detect unused code elements in .cs files and provides a quick way to clean them up. It's especially helpful for: Refactoring old codebases Removing noise before code reviews Keeping things lean and maintainable ⚙️ How It Works Under the hood, the tool: Parses the solution or project using Roslyn APIs. Analyzes syntax trees and semantic models to find symbols (variables,function and classes(whose all methods have 0 reference).) that are declared but never referenced. Comments or flags them for your review. It's like having an assistant that knows your code well enough to do spring cleaning for you.

Have you ever returned to a .NET project only to find it cluttered with unused code—methods, variables, or even entire classes that serve no purpose anymore? If so, you're not alone. As projects grow and evolve, it's easy for dead code to accumulate, quietly bloating your codebase and making maintenance harder.

That's why I built Roslyn Unused Code Remover—a lightweight CLI tool that automatically identifies and removes unused code from your C# projects using the Roslyn compiler platform.

✨ What It Does

This tool leverages the power of Roslyn analyzers to detect unused code elements in .cs files and provides a quick way to clean them up. It's especially helpful for:

  • Refactoring old codebases
  • Removing noise before code reviews
  • Keeping things lean and maintainable

⚙️ How It Works

Under the hood, the tool:

  1. Parses the solution or project using Roslyn APIs.
  2. Analyzes syntax trees and semantic models to find symbols (variables,function and classes(whose all methods have 0 reference).) that are declared but never referenced.
  3. Comments or flags them for your review.
