CSharp Language Support Quickstart

Quickstart: C# Code Indexing

Index a C# Project

1. Start doc-serve

cd /path/to/my-csharp-project
doc-serve start

2. Index with code support

doc-serve index /path/to/my-csharp-project/src --include-code

The system automatically detects .cs and .csx files and parses them using AST-aware chunking.

3. Query C# code

# Search for a specific method
doc-serve query "GetUserById method"

# Filter to C# results only
doc-serve query "authentication" --language csharp

4. Verify C# indexing

doc-serve status
# → Indexed: 1,234 chunks from 56 files
# → Languages: python (20), csharp (15), typescript (21)

What Gets Extracted

For a C# file like:

/// <summary>
/// Manages user authentication and session handling.
/// </summary>
public class AuthService
{
    /// <summary>
    /// Authenticates a user by email and password.
    /// </summary>
    /// <param name="email">User's email address</param>
    /// <returns>Authentication result with session token</returns>
    public async Task<AuthResult> LoginAsync(string email, string password)
    {
        // ...
    }
}

Doc-serve extracts:

• Symbol name: LoginAsync
• Symbol kind: method_declaration
• Parameters: string email, string password
• Return type: Task<AuthResult>
• Docstring: "Authenticates a user by email and password."
• Line numbers: start/end line of the method

Supported C# Constructs

Construct	Extracted As
Classes	class_declaration
Methods	method_declaration
Constructors	constructor_declaration
Interfaces	interface_declaration
Properties	property_declaration
Enums	enum_declaration
Structs	struct_declaration
Records	record_declaration
Namespaces	namespace_declaration

Verification Checklist

• .cs files are detected and loaded during indexing
• .csx files are also detected and loaded
• C# code is chunked at class/method boundaries (not arbitrary line splits)
• Symbol metadata (name, kind, parameters, return type) is present in query results
• XML doc comments (///) are extracted as docstring metadata
• --language csharp filter returns only C# results
• C# files with syntax errors fall back to text-based chunking (not skipped)
