WebService SVC / site web : Erreur 415 "application/json; charset=utf-8"

Bonjour à tous,

je développe un nouveau site web chez moi, ce site est censé appeler un webservice.
Jusque là, rien de bien fantastique !

Mon webservice est accessible en local chez moi à l'adresse http://localhost:51819/Service2.svc (j'ai accès au
également au wsdl)

Mon site web est accessible au même moment à l'adresse http://localhost:51819/EspacePerso

Seulement quand j'essai d'accéder à une des méthodes du webservice j'ai le message suivant qui est déclenché :

Citation:

"Service call failed: 415 | Cannot process the message because the content type 'application/json; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'".

Je n'arrive pas à trouver d'où peut venir le problème.

Merci d'avance à ceux qui prendront le temps de jeter un oeil à mon problème.

Voici mon javascript d'appel de mon webService

        varUrl = "deleteExercice";
        varData = '{"idExercice": "' + idExercice + '"}';
        varContentType = "application/json; charset=utf-8";

}
 
function CallService(/*funct*/) {
    $.ajax({
        type: varType,  //GET or POST or PUT or DELETE verb
        url: 'http://localhost:51819/Service2.svc/' + varUrl,    // Location of the service
        data: varData,  //Data sent to server
        contentType: varContentType,    // content type sent to server
        //dataType: varDataType,          //Expected data format from server
        processdata: varProcessData,    //True or False
        success: function (msg) {
            alert('ok');//if (funct) funct(msg.d);
        },
        error: ServiceFailed// When Service call fails
    });
}
 
function ServiceFailed(result) {

    Type = null;
    varUrl = null;
