POST to WCF from Fiddler succeeds but passes null values

Question

I\'ve followed this video series on WCF and have the demo working. It involves building a WCF service that manages student evaluation forms, and implements CRUD operations

Answer 1

For POST you need to use BodyStyle = WebMessageBodyStyle.Bare NOT
WebMessageBodyStyle.Wrapped

    [OperationContract]
    [WebInvoke(RequestFormat = WebMessageFormat.Json,ResponseFormat = WebMessageFormat.Json,UriTemplate = "eval",BodyStyle = WebMessageBodyStyle.Bare)]
    void SubmitEval(Eval eval);
