Can we use wcf WsDualHttpBinding(DUPLEX comm) for communicating between two different websites in asp.net

Question

I want to make duplex communication(CHAT like application) between two different websites in asp.net. I have seen lot of demos of duplex communication with two windows application (nettcpbinding) binding.

But I want to achieve this with two websites. Can it be achieved?

Answer 1

It doesn't make any difference, just as you create a winforms app that has a reference to a WCF service, you can add a reference to your WCF service from your ASP.NET project as well.

However, if you want to make a chat like application (generally, any real-time communication with your web users), I recommend taking a look at SignalR.

Update:
If you're insisting on using WCF for implementing this, take a look at this CodeProject article which explains exactly what you're trying to achieve.
