I have the same problem as guys had. I try to use chunking for WSDualHttpBinding. I create binding elements from in the following way:
public override BindingElementCollection CreateBindingElements()
{
WSDualHttpBinding wsHttpBinding = new WSDualHttpBinding();
BindingElementCollection beCollection = wsHttpBinding.CreateBindingElements();
beCollection.Insert(6, be);
return beCollection;

//BindingElementCollection col = new BindingElementCollection();
//col.Add(new TransactionFlowBindingElement());
//col.Add(rsbe);
////col.Add(new TransportSecurityBindingElement());
//col.Add(SecurityBindingElement.CreateAnonymousForCertificateBindingElement());
//col.Add(cdbe);
//col.Add(owbe);
//col.Add(new WindowsStreamSecurityBindingElement());
//col.Add(encbe);
//col.Add(be);
//col.Add(httpbe);
//return col;
}

I’m trying to integrate ChunkingChannel with WsFederationHttpBinding.

Is it my stack:

…….

But it fails. Is it possible to do what I would?

Thanks in advance
