I was testing out my own WCF REST Service using Fiddler and was getting error response “The incoming message has an unexpected message format ‘Raw'”.<\/p>\n

After spending time diagnosing the message the clue was, the WCF was getting a request with no content type.<\/p>\n

My contract was specifically expecting the request format to be XML using the following attribute<\/p>\n

RequestFormat = WebMessageFormat.Xml<\/pre>\n
Hence added the content type as “application\/xml” and things went fine.<\/p>\n
