This project targets to port Charles Cook's XML-RPC library to .NET.

Do not wonder, the original library / website is no longer available.

All libraries are available on nuget.org

• Horizon.XmlRpc.Core
• Horizon.XmlRpc.Client
• Horizon.XmlRpc.Server

The library, respectively its main components were ported to .NET Standard. The APIs haven't changed. In addition, the library was refactored into three dedicated assemblies.

• Horizon.XmlRpc.Core Holds all the core members and contracts required by a XML-RPC servive as well as a XML-RPC client
• Horizon.XmlRpc.Client
  Holds the ported XmlRpcProxyGen, the IXmlRpcProxyinterface and their dependencies
• Horizon.XmlRpc.Server
  Holds the ported XmlRpcListenerService, the documentation generator and their dependencies used to host a XML-RPC service in any .NET Standard compatible application.

This section gives you a brief introduction on how to write a service and how to consume the service with a generated client proxy.

To get a full example of a running client and server, please have a look at the Samples, based on .NET 8 BackgroundService.

First define a contrat for your service. This will be used by the client proxy and implemented from the service.

using Horizon.XmlRpc.Core;

public interface IAddService
{
    [XmlRpcMethod("Demo.addNumbers")]
    int AddNumbers(int numberA, int numberB);
}

Then define your service...

using Horizon.XmlRpc.Server;

public class AddService : XmlRpcListenerService, IAddService
{
    public int AddNumbers(int numberA, int numberB)
    {
        return numberA + numberB;
    }
}

and start a new listener.

using System.Net; 

var service = new AddService();
var listener = new HttpListener();
listener.Prefixes.Add("http://127.0.0.1:5678/");
listener.Start();

while (true)
{
    var context = listener.GetContext();
    service.ProcessRequest(context);
}

The service also provides an automatically generated documentation by browing to the opened enpoint http://127.0.0.1:5678/

To consume the service, simply create a client proxy...

using Horizon.XmlRpc.Client;

public interface IAddServiceProxy : IXmlRpcProxy, IAddService
{
}

and use the proxy to call its methods.

using Horizon.XmlRpc.Client;

var proxy = XmlRpcProxyGen.Create<IAddServiceProxy>();
proxy.Url = "http://127.0.0.1:5678";

var result = proxy.AddNumbers(3, 4);
Console.WriteLine("Received result: " + result);

// Prints 7 to the output
