Aider C# Development Configuration

Optimized Aider configuration for C# development with automatic code formatting, linting, and testing.

Overview

This configuration sets up Aider to work seamlessly with C# projects by:

Instructions

1. **Prerequisites**: Install CSharpier globally:

```bash

dotnet tool install -g csharpier

```

See https://csharpier.com/docs/CLI for details.

2. **Create Configuration File**: Place this content in `.aider.conf.yml` at your repository root or home directory:

```yaml

Max number of tokens to use for repo map (0 to disable)

map-tokens: 1024

Files to always include in context

file: [.editorconfig, Directory.Build.props]

Lint command for C# (CSharpier formatter)

lint-cmd: "dotnet csharpier --no-msbuild-check --fast --skip-write "

Enable automatic linting after changes

auto-lint: true

Test command (dotnet build to catch compilation errors)

test-cmd: "dotnet build"

Enable automatic testing after changes

auto-test: true

Enable prompt caching to reduce token costs

cache-prompts: true

More precise cached token pricing (disables streaming)

no-stream: true

```

3. **Verify Setup**: Run Aider in your project directory. It should automatically:

- Load `.editorconfig` and `Directory.Build.props` for context

- Format code with CSharpier after each change

- Run `dotnet build` to verify compilation

- Cache prompts for cost optimization
