Nerdbank.JsonRpc

Nerdbank.JsonRpc is a NativeAOT-safe .NET library for building strongly typed JSON-RPC clients and servers over MessagePack or UTF-8 JSON.

Features

  • Strongly typed RPC: Register local targets and issue typed requests or notifications.
  • Generated client proxies: A built-in source generator creates interface-backed proxies with positional or named arguments.
  • MessagePack or JSON: MessagePack (default, length-header or self-delimiting framing) or UTF-8 JSON (newline-delimited or Content-Length framing).
  • Peer-to-peer: One connection can both expose local methods and invoke remote ones.
  • Batching: Send independent requests and notifications in one JSON-RPC payload.
  • Cancellation and robust error handling: Propagates cancellation and distinguishes malformed protocol messages from application failures.
  • Ordered dispatch: Inbound requests start in the order sent, while running concurrently.
  • Deadlock mitigation: Propagates JoinableTaskFactory context across processes, compatible with StreamJsonRpc.
  • Exotic types: Marshal interfaces, observers, progress, streams, and async sequences by reference.

Quick start

Define a contract shared by both parties:

using Nerdbank.JsonRpc;
using PolyType;

[GenerateJsonRpcProxy]
[GenerateShape(IncludeMethods = MethodShapeFlags.PublicInstance)]
public partial interface ICalculator
{
    ValueTask<int> AddAsync(int a, int b, CancellationToken cancellationToken);
}

public class Calculator : ICalculator
{
    public ValueTask<int> AddAsync(int a, int b, CancellationToken cancellationToken) => new(a + b);
}

Connect over any bidirectional stream, expose a local target, and call the remote party through a proxy:

using Nerdbank.Streams;

using JsonRpc rpc = new(new JsonRpcMessagePackChannel(stream.UsePipe()));

// Expose a local target the remote party can call.
rpc.AddRpcTarget<ICalculator>(new Calculator());
rpc.Start();

// Invoke a method on the remote party.
ICalculator remote = rpc.Attach<ICalculator>();
int sum = await remote.AddAsync(1, 2, CancellationToken.None);
