使用wsDualHttpBinding的WCF是否可以在Https上？

Question

I implemented a simple WCF/WPF project to try out the push notification function of WCF . From searches online, they are mostly implemented via callback and using the binding wsDualHttpBinding .

However, when trying to implement this PoC project into my main project. I realise the existing WCF service is using Https and I can't seem to find a way to enable transport security mode for wsDualHttpBinding as compared to the existing wsHttpBinding .

If the above problem is not solvable, is there another way to implement push notification over Https on WCF ?

If we want to use SSL protocol to encrypt our duplex communication, depending on the practical scenario, we could consider the following binding.

• NetTcpbinding: mainly designed binding for the intranet. If the communication is only within the LAN, we could use this binding, it supports duplex communication and SSL protocol with a certificate. https://docs.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/wcf/security-of-nettcpbinding

• NetHttpsbinding: It is a duplex communication across the Internet based on websocket protocol, and supports the use of certificates to encrypt communications.

  Refer to the below example.
