problem with Duplex System using wsDualHttpBinding

Hello News Group,

I'm playing with WCF and was able to build a properly working Duplex system
using netTcpBinding.
However, when changing the configuration to wsDualHttpBinding I get an error
message on the host side when trying
to call back the client proxy:

ProtocolException {"The remote server returned an unexpected response: (400)
Bad Request."}
->InnerException: WebException{"The remote server returned an error: (400)
Bad Request."}

Getting the client proxy reference works fine with:

_client =
OperationContext.Current.GetCallbackChannel<ISpectralServiceCallbackContract>();

calling

_client.SomeOperation();

wails with the upper exception.

My Host Config File (Done with Service Conf. Editor) looks like:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="NewBehavior" />

As I said, it works pretty well using the net.tcp channel, but it fails with
dual http.

Does anybody know what to change in order to get it to work?

Thanks in advance,

Just in case you might struggle yourself with it. I had to increase the
transfer buffers since I was passing large arrays.
Now it works perfect.
