Hi

I have a few basic questions regarding WCF. If this is not the correct 
newsgroup please advise me where to ask.

In a WCF service, if no [ServiceBehavior] attribute is supplied, does that 
mean that the service is "per call"?

And does "per call" mean that a new instance of the ServiceContract class 
is created for every call to each and every method in the ServiceContract 
class? 

And do these service instances run in their own application domain - which 
is then torn down again when the service method exits? Can I risk that two 
Service objects would be instantiated in the same application domain?

Furthermore, does SessionMode.Allowed mean that a "session" is maintained 
between the calls to the service class (much the same as a http-session 
object in a web-application)?


Thanks,
Peter
