Hi,

I have a winform client which consumes a WCF service. I have a single
service client(proxy) at the winform side, but spread the service calls into
multiple threads so that they can do works concurrently. My confusion is, as
all threads share the same proxy, will one thread block another while calling
a long running service? Is this related to the service concurrent
configuration?

Thanks.

Daniel

Hi Daniel,

As for WCF client proxy, it seems a bit different from previous webservice
client proxy class. WCF proxy is somewhat a heavy-weight one which means if
we'll frequently issue method call in concorrent threads, it would be
costly to always create a new proxy instance when making a method call.
Here is some blog article which describes manually using a proxy pool to
address large concurrent WCF method call case:

Yes it is - I believe WCF now supports non-blocking calls.
