\viewkind4\uc1\pard\lang2052\f0\fs20 Hi Daniel,
\par
\par 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:

\par Subject: WCF concurrent call on client
\par Date: Sun, 9 Dec 2007 17:50:00 -0800
\par Hi,
\par
\par I have a winform client which consumes a WCF service. I have a single
\par service client(proxy) at the winform side, but spread the service calls into
\par multiple threads so that they can do works concurrently. My confusion is, as
\par all threads share the same proxy, will one thread block another while calling
\par a long running service? Is this related to the service concurrent
\par configuration?
\par
\par Thanks.
\par
