It's shameless-plug-time, I'm afraid: http://github.com/regularfry/xmlrpc_annotations A library I knocked together a while ago to generate C# interface files for an XMLRPC service by annotating the Ruby source. It could be extended to other languages, but I never bothered. I used it to serve the interface file directly from http://example.com/service/Foo.cs http://example.com/service/Foo.cs. Works nicely for what it does. To bring this comment lurching somewhat closer to the topic at hand, would this be a feasible approach for RESTful interfaces?
