D'erreur lorsque vous essayez de consommer service WCF retour fichier

Un de mes méthodes retourne byte[], d'un fichier. Toutes les autres méthodes retournent une chaîne d'objets ou d'objets personnalisés

Je peux afficher le WSDL via un navigateur et que j'ai utilisé WCfExtras, je peux même voir la documentation.

Dans mon appli de test, C# une application web, j'ajoute la référence à mon service, hébergé sur un serveur de test. J'obtiens une erreur en tant que telle:

     The document was understood, but it could not be processed.
  - The WSDL document contains links that could not be resolved.
  - There was an error downloading ...
  - Unable to connect to remote server
  - No connection could be made because the target machine actively refused it

    Content Type application/soap+xml; charset=utf-8 was not supported by service .  The client and service bindings may be mismatched.
    The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..
    If the service is defined in the current solution, try building the solution and adding the service reference again.

C'est mon application.config

<?xml version="1.0" encoding="utf-8" ?>

<add name="TestApp.Properties.Settings.TestDBConnectionString"
connectionString="Data Source=192.168.2.130;Initial Catalog=TestDB;Persist Security Info=True;User ID=sa;Password=xerox"

Des idées sur comment je pourrais résoudre ce problème? Je devrais avoir 2 différentes liaisons, l'une des méthodes de retour non octets[] et Mtom pour la méthode de retour byte[]? Si oui, comment applique-t-on les liaisons par la méthode exposée?

Essayé de courir avec WcfTestClient.exe et c'est l'erreur
