 From the traceback it looks like your program is connecting to the 
XML-RPC server but the method you want to invoke is not known by the 
server. Probably something to do with case sensitivity or namespace.

I downloaded the package from http://www.xml-rpc.net. No need to build 
it as there are pre-built dll files in the bin directory which seem to 
work fine with mono.

So I built your example and couldn't figure out why it didn't work and 
after some swearing I delved into the docs and found XmlRpcProxyGen 
which will create a callable proxy from an interface. Pretty neat. Try 
this.....


using System;
using CookComputing.XmlRpc;

struct SumAndDiff {
     public int sum;
     public int difference;
}

[XmlRpcUrl("http://www.cookcomputing.com/xmlrpcsamples/math.rem")]
interface IMath
{
     [XmlRpcMethod("math.Add")]
     int Add(int a, int b);
     [XmlRpcMethod("math.Divide")]
     int Divide(int a, int b);
     [XmlRpcMethod("math.Multiply")]
     int Multiply(int a, int b);
     [XmlRpcMethod("math.Subtract")]
     int Subtract(int a, int b);
     [XmlRpcMethod("math.SumAndDifference")]
     SumAndDiff SumAndDifference(int a, int b);
}


class Test
{
     static void Main()
     {
         IMath mathProxy = (IMath)XmlRpcProxyGen.Create(typeof(IMath));

         Console.WriteLine("5 + 4 = {0}", mathProxy.Add(5, 4));

         SumAndDiff sumAndDiff = mathProxy.SumAndDifference(10, 15);
         Console.WriteLine("Sum = {0}, Difference = {1}",
                           sumAndDiff.sum, sumAndDiff.difference);
     }
}
