ServiceStack is a good alternative which includes built-in support for SOAP which automatically generates WSDLs, XSDs and Schema Descriptions from your Service Definitions, available from your auto-generated Metadata Pages.
ServiceStack also offers a better alternative to WCF's Add Service Reference which can generate a typed API from just a URL using Add ServiceStack Reference.
