Claude Code SDK for C#

A .NET SDK for interacting with Claude through the Claude Code CLI, providing both one-shot queries and interactive client sessions.

This file (README.md) is generated by claude code.

Installation

Install via NuGet:

dotnet add package ClaudeCodeSdk

Prerequisites

  • .NET 8.0 SDK
  • Claude Code CLI: npm install -g @anthropic-ai/claude-code

Quick Start

One-shot Query

using ClaudeCodeSdk;

var messages = ClaudeQuery.QueryAsync("What is the capital of France?");
await foreach (var message in messages)
{
    Console.WriteLine(message.Content);
}

Interactive Client

using ClaudeCodeSdk;

using var client = new ClaudeSdkClient();
await client.ConnectAsync();

await client.SendMessageAsync("Hello Claude!");

await foreach (var message in client.ReceiveMessagesAsync())
{
    if (message is AssistantMessage assistantMsg)
    {
        Console.WriteLine($"Claude: {assistantMsg.Content}");
    }
}

Architecture

The SDK implements a dual-pattern architecture:

  • One-shot Queries - Fire-and-forget pattern for simple queries
  • Interactive Client - Long-lived bidirectional communication with session management

Message Types

  • AssistantMessage - Claude's responses
  • UserMessage - User input
  • SystemMessage - System notifications
  • ResultMessage - Conversation end marker

Content Blocks

  • TextBlock - Plain text content
  • ToolUseBlock - Tool invocations
  • ToolResultBlock - Tool execution results
  • ThinkingBlock - Claude's reasoning
