Claude SDK for C#

NuGet Version

As of version 10+, the Anthropic package is now the official Claude SDK for C#. Package versions 3.X and below were previously used for the tryAGI community-built SDK, which has moved to tryAGI.Anthropic. If you need to continue using the former client in your project, update your package reference to tryAGI.Anthropic.

The Claude SDK for C# provides access to the Claude API from C# applications.
