Anthropic.SDK is an unofficial C# client designed for interacting with the Claude AI API. This powerful interface simplifies the integration of the Claude AI into your C# applications.

To effectively utilize the Anthropic SDK in C#, you need to follow a structured approach to make API calls. This section will guide you through the essential steps, including installation, authentication, and making requests. First, ensure you have the .NET SDK installed on your machine. You can create a new project using the following command: dotnet new console -n AnthropicExample cd AnthropicExample

This library for the Anthropic API is meant to simplify development in C# for Anthropic users. This is an unofficial SDK for the Anthropic API.

To send a request to the Anthropic API, build an instance of some Params class and pass it to the corresponding client method. When the response is received, it will be deserialized into an instance of a C# class. For example, client.Messages.Create should be called with an instance of MessageCreateParams, and it will return an instance of Task<Message>. The SDK defines methods that return response "chunk" streams, where each chunk can be individually processed as soon as it arrives instead of waiting on the full response.

April 10, 2025 - The C# SDK is based on an existing community project called mcpdotnet, originally started by Peder Holdgaard Pederson. Microsoft acknowledged the groundwork laid by Pederson and other contributors, which helped shape the foundation for this release. David Fowler, a distinguished engineer at Microsoft, noted: Most of the credit goes to Peder Holdgaard Pedersen who we teamed up with after he built a great implementation! Initially introduced by Anthropic in late 2024, MCP has seen increasing adoption across AI platforms.

3 weeks ago - This is a “serverless” integration this means you use Azure’s credentials (API key or Entra ID token) to call the Claude Messages API at the Azure endpoint. The integration supports multiple languages – you can call Claude from Python, JavaScript, or C# SDKs with either API key or Azure AD authentication. In C#, this typically involves using either Anthropic’s .NET SDK or Microsoft Extensions for AI (MEAI).
