Symptoms
When trying to register a WCF service using the SmartObject Service Tester under the WCF Endpoints service, you receive an error like "The document at the url [SERVICE URL] was not recognized as a known document type. The error message from each known type may help you fix the problem: - Report from 'WSDL Document' is 'There is an error in XML document (1, 40).'. - was not expected."
Diagnoses
This error occurs while trying to register a REST service endpoint with the WCF service broker.
Resolution
Unfortunately at this time the WCF service broker only supports WCF endpoints, and does not currently support REST endpoints. The REST service broker is currently in Beta and will be available in a future release.
