any equivalent binding like wsDualHttpBinding, which works for WIF for federated security?

Question

I'm looking to setup a wsDualHttpBinding wcf endpoint to provide WCF eventing. However, the rest of my application uses WIF to provide authN/authZ support via Claims security. For those endpoints protected by WIF, I'm using WS2007FederationHttpBinding

Is there any pre-existing binding like WS2007FederationHttpBinding, except with duplex support?

yep, pretty much the same question. no correct answers there either. — savagepanda
Short answer: I don't think there is an option that supports duplex. — Garrett Vlieger
yup, looks like custom binding maybe the only option. another possible duplicate: stackoverflow.com/questions/10499228/… — savagepanda

Seems like there is no duplex binding for federated wcf.

Thus I'm now on plan B. use existing WS2007FederationHttpBinding, and create a long polling WCF operation to simulate duplex behavior. One side benefit of this approach is that its firewall friendly.
