Getting started with C# and RPC connecting to a server running Apache2/PHP5

Question

I'm a total beginner with C#, and having worked on server-side PHP programming for the last 6 years I have almost forgot what it's like to create a client-side program. However, I would now like to create a small client-side program communicating with PHP on the server. If I understand it correctly, SOAP is what MS natively supports. However, this is not natively supported in PHP, why I would like to stick to plain XML-RPC. But my question is, how do I get started with Visual C# 2005 (Express Edition) and XML-RPC? What do I need? Can and find a super-simple example somewhere?

Please note that I'm not yet fluid in configuring the Visual C# environment.

Thanks in advance,
