# ReSharper Code Cleanup vs Roslyn Analyzers: Which should you use in .NET projects?

When managing code quality and enforcing style guidelines in modern .NET projects, developers often choose between **ReSharper Code Cleanup** and native **C# Roslyn Analyzers** with `.editorconfig` files. Both tools serve similar goals but differ significantly in ecosystem integration and execution.

## Comparing ReSharper and Roslyn Analyzers

Consider the following key differences between both tools:

- **Execution Context:** Roslyn Analyzers run natively during MSBuild, making them ideal for CI/CD enforcement. ReSharper Code Cleanup traditionally runs within Visual Studio or via JetBrains command-line tools.
- **Configuration:** Roslyn relies heavily on standard `.editorconfig` files, whereas ReSharper uses layered `.DotSettings` files (though ReSharper can also read `.editorconfig`).
- **Rule Depth:** ReSharper offers hundreds of advanced structural inspections and quick-fixes beyond standard compiler-level analysis.

### Example EditorConfig Rule setup

Here is an example of an `.editorconfig` entry that both Roslyn and modern ReSharper installations respect:

```
# Enforce var keyword usage for explicit types
[*.cs]
csharp_style_var_for_built_in_types = true:suggestion
csharp_style_var_when_type_is_apparent = true:suggestion
```

## Recommendation

For most modern .NET teams, using **Roslyn Analyzers** with `.editorconfig` as the primary build-level baseline combined with **ReSharper** for local interactive refactoring yields the best experience.
