WCF Proxies

[james]

Hi Guys,

Is it expensive to create proxies in WCF? I always create new proxy
instances (when not using sessions) so I don't have to worry about a
proxy falling into a Faulted state. I started an application that
where performance is an issue, and I was curious if creating new
proxies is going to create a noticeable slowdown.

Thanks,
James

James,

I would think that this depends on whether or not they are open, or
closed. If you have an open proxy, then you probably have a resource that
you don't want to hold onto for too long (this would depend on the
transport, whether it is a named pipe, a socket, msmq, etc, etc).

I don't think that it's an issue generally though. If you are thinking
of sharing a proxy, then I would make sure that you have threadsafe access
to the proxy, especially if you are performing callbacks.

Overall though, I would create and dispose the proxies as needed.
