Best way to access remote data via XML-RPC?

I'm trying to connect 3ds Max to a server using XML-RPC calls. Presumably I'll need to do this with a dotNet library but I've never done this before (on any platform) so I'm open to suggestions.

Google results indicate www.xml-rpc.net (3rd party library) is where I should look but I'd much rather do this w/o plugins if at all possible. Does anybody have any ideas?
