There was no channel that could accept the message with action

When I access my webservice via WcfTestClient, it returns me a few hundred results in a few seconds, so my webservice works fine.

Now, when I try to access it via my application, it throws me all kinds of errors.
My webservice is on a website hosted with Visual Studio, I access it on localhost, and when I navigate to the endpoint it shows me no error (just the message on how to generate a proxy class).
I already have another webservice+app, which work fine thanks to the kind gentlemen there : WCF webservice - can't use it in production . Obviously I copy-pasted the config files, but no luck.
The proxy class is auto-generated by Visual Studio, via "Add Webservice Reference".

I have exactly the symptoms described there : http://webservices20.blogspot.com/2009/04/which-binding-to-use-wshttpbinding-or.html but this site does not suggest concrete solutions, so it's not of much help to me.

The IPushMail service interface (in a DLL) :

Imports System.ServiceModel
Imports System.Collections.Generic
Imports System.ServiceModel.Web

<ServiceContract()> _
Public Interface IPushMail

    <OperationContract()> _
    <WebGet(UriTemplate:="GetEmails")> _
    Function GetEmails() As List(Of CMS.Mail.MailSerialiserPushMail)

    <OperationContract()> _
    <WebGet(UriTemplate:="IncrementerNumero")> _
    Function Incrementer() As Boolean

End Interface

The PushMail webservice class (in the App_Code folder of the site) :

Imports System.Collections.Generic

Public Class PushMail
    Implements IPushMail

    Public Function GetEmails() As List(Of CMS.Mail.MailSerialiserPushMail) Implements IPushMail.GetEmails
        Dim mails As New List(Of CMS.Mail.MailSerialiserPushMail)
        ' get mails
        Return mails
    End Function

    Public Function Incrementer() As Boolean Implements IPushMail.Incrementer
        ' update record
        Return True
    End Function

End Class

The PushMail app :

Imports System.Collections.Generic
Imports System.Text

Module PushMail

    Sub Main()
        Dim pmClient As New PushMailService.PushMailClient()
        Dim mails As List(Of PushMailService.MailSerialiserPushMail) = pmClient.GetEmails()
        For Each m In mails
            ' do stuff
        Next
        If (pmClient.Incrementer()) Then
            Console.WriteLine("FINI")
        End If
        pmClient.Close()
    End Sub

End Module

And here are the errors I get :

The app throws a generic message : "An unsecured error or incorrectly secured fault was received from the other party. See the inner fault exception for the fault code and detail". The InnerException is not of much more help : "The message could not be processed. This is most likely because the action xxx is incorrect or because the message contains an invalid expired security context token or because there is a mismatch between bindings".

The trace log is a bit more detailed. It starts by giving me two similar warnings, both saying "The specified domain either does not exist or could not be contacted".

It looks like the domain (localhost) cannot be contacted, but I can access it with WcfTestClient ! I really don't get it...

Thanks for your help...

OK, I have found the solution... There was establishSecurityContext="true" in the web.config, and establishSecurityContext="false" in the app.config. I set it to true in the app.config, and now it works...
