[WCF] Some basic questions

[akhileshbc]

Hi guys

I have gone through some video & web tutorials and have some doubts.

1. Is it possible to create more than one ServiceContract ?
2. Is it possible to create more than one DataContract ?
3. I heard about SelfHosted services. So, it would run when the server application runs. Is it ?
4. If we the server needs to send some messages to the clients, how is it done ? What I have seen in the tutorials is calling the functions of the service which is being hosted in the server.

Thanks

1 + 2: Yes that is no problem at all
3: That is correct, the wcf service is started from the application/windowsservice
4:that can be done using a duplex bindng

I'll do some googling for "duplex binding" and will let you know if I have any other doubts.
