WCF Service Reference generates an empty reference.cs due to DuplexBinding

Question

I have WCF service. Here is configuration

Answer 1

The polling duplex HTTP binding is only supported by Silverlight clients. Since you're using svcutil to generate the reference, I assume you're building a "normal" (i.e., non-SL) client for the server, so that won't work.

If you want to use a duplex binding on a non-Silverlight application, you can take a look at either the wsDualHttpBinding or netTcpBinding.
