Project Description
JSON-RPC.Net is a high performance Json-Rpc 2.0 server, leveraging the popular JSON.NET library. The server communicates easily with JavaScript clients and works with the Jquery JsonRpc2 plugin, and includes support for JSONP.

The source also includes a client library built on Reactive Extensions to support .NET and Silverlight clients. There is also source for an early Windows Phone 7 client (it needs unit tests).

The Json-Rpc server allows asmx style setup and configuration.

There are some simple test client and server projects. With the test server started, then the Test client should pass all its tests.



Some simple performance test results running client and server locally does not include network latency.
Metrics were recorded client side, so a "request" is a request and response from the server, including serialization.

Server Side
Hello World service
namespace TestServer{
    using System;
    using AustinHarris.JsonRpc;

    public class HelloWorldService: JsonRpcService{
        [JsonRpcMethod]
        private string helloWorld(string message){
            return "Hello World "+ message;
        }
    }
}

Hello World service registration (Global.asax.cs)
using System;

namespace JsonRpcTest{
    public class Global : System.Web.HttpApplication {
        private static HelloWorldService service = new HelloWorldService();
    }
}

Json-Rpc handler setup (web.config in an asp.net project) 
<?xml version="1.0"?>
<configuration>
    <system.web>
      <httpHandlers>
        <add type="AustinHarris.JsonRpc.JsonRpcHandler" verb="*" path="*.rpc"/>
      </httpHandlers>
    </system.web>  
</configuration>

Client Side
public void TestHelloWorld() {
    var client = new AustinHarris.JsonRpc.JsonRpcClient(new Uri("http://localhost:57956/json.rpc"));
    var myObs = client.Invoke<string>("helloWorld", "My Message", Scheduler.TaskPool);

    myObs.Subscribe(
        onNext: _ => {
            Console.WriteLine(_.Result);
        });
}
JsonRpcClient.Invoke has the signature:
public IObservable<JsonResponse<T>> Invoke<T>(string method, object arg, IScheduler scheduler)
So that when you call it, it follows this format:
Invoke<ReturnType>("RpcMethodName",RpcParameter, ConcurrencyScheduler)
