WCF REST Service: Request object is null

Question

I'm trying to send an object to my REST Service but the object is not mapped properly.

I have defined my contract as:

<OperationContract(),
    WebInvoke(UriTemplate:="/SendNotification",
              ResponseFormat:=WebMessageFormat.Json, RequestFormat:=WebMessageFormat.Json, BodyStyle:=WebMessageBodyStyle.Bare,
              Method:="POST")>
Function SendNotification(ByVal data As Models.Notification) As Boolean

Model:

Namespace Models
    <DataContract()>
    Public Class Notification
        <DataMember(Name:="ApplicationID")>
        Public Property ApplicationID As String
        <DataMember(Name:="PortalIDs")>
        Public Property PortalIDs As String
        <DataMember(Name:="Message")>
        Public Property Message As String
        <DataMember(Name:="Badge")>
        Public Property Badge As String
    End Class
End Namespace

And then I'm posting my data like:

var o = {data: { ApplicationID: "2", PortalIDs: "pid", Message: "THis is a test", Badge: "3"}};

$.ajax({
    type: "POST",
    url: url + "/SendNotification",
    contentType:"application/json",
    data: JSON.stringify(o),
    processData : false
}).done(function( msg ) {

});

The generated request like:

POST http://localhost:62530/Services/Notification/NotificationWS.svc/SendNotification HTTP/1.1
Host: localhost:62530
Connection: keep-alive
Content-Length: 87
Cache-Control: no-cache
Pragma: no-cache
Origin: http://localhost:62530
X-Requested-With: XMLHttpRequest
Content-Type: application/json
Accept: */*

DNT: 1
Referer: http://localhost:62530/D.html
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-GB,en;q=0.8,ca;q=0.6,fr;q=0.4,pt;q=0.2,es;q=0.2

{"data":{"ApplicationID":"2","PortalIDs":"pid","Message":"THis is a test","Badge":"3"}}

The function is called, and a data object is there, but it's properties are null

I've been looking into similar questions like Sending JSON to WCF Rest Service - object is always null and how to send custom object to WCF REST Service in browser based url with no luck

Thanks

Can you provide also the Models.Notification class? Your call seems to me ok. — kostas ch., Mar 12 '14 at 10:01
That's strange to me, have you tried to call your method through .net? I mead by using HttpWebRequest or WebClient. — kostas ch., Mar 12 '14 at 10:10
If success then see in fiddler how the call constructed. I think it will be something silly. I have face such problems before and always was something totally silly :) — kostas ch., Mar 12 '14 at 10:19

Try changing the data you are posting like this:

var o = {ApplicationID: "2", PortalIDs: "pid", Message: "This is a test", Badge: "3"};

I seem to remember that when I was using the WCF rest thingies that I never had to specify the variable name in my HTTP Request.

I think changing WebMessageBodyStyle.Bare to WebMessageBodyStyle.Wrapped can do the trick in your case.
