Host accessing service functionality and CallBacks with InstanceContextMode.Single

Hi,



I have a service hosted inside a windows application.

I also a have a client requesting information thru the service, I
created a proxy from the service thru the 'Add service reference' menu
item.

Once in a while I need the windows application hosting the service to
also request some information from the service, so I created a proxy in
the windows application with the 'Add service reference' as well. Is
this standard practice?



Ultimately, I need both client and host to be able to query services.



Another question that I have is that if it's possible to have callbacks
in a service which is declared as InstanceContextMode.Single:



<ServiceBehavior(ConcurrencyMode:=ConcurrencyMode.Multiple,
InstanceContextMode:=InstanceContextMode.Single)>



Thanks,

Mike

When you add service reference you are technically creating a proxy to
access the service.

Since you have the Assembly you should be able to get to it directly.
Moreover it is sign of "need for re-architecting" if the host has to do a
reference to its own service.

You can use InstanceContextMode.Single in a wsDualHttpBinding protocol.
