It works over Stream, WebSocket, or System.IO.Pipelines pipes, independent of the underlying transport.

Bonus features beyond the JSON-RPC spec include:

  1. Request cancellation
  2. .NET Events as notifications
  3. Dynamic client proxy generation
  4. Support for compact binary serialization via MessagePack
  5. Pluggable architecture for custom message handling and formatting.

Learn about the use cases for JSON-RPC and how to use this library from our documentation.
