<p>Looking to hear from people who are using WCF in an enterprise environment.</p>

<p>What were the major hurdles with the roll out?
Performance issues?
Any and all tips appreciated!</p>

<p>Please provide some general statistics and server configs if you can!</p>

WCF can be
configuration hell
. Be sure to familiarize yourself with its
diagnostics and svcTraceViewer
, lest you get madenning cryptic, useless exceptions. And watch out for the generated client's
broken implementation of the disposable pattern
.
