The following method (in which I hopefully did not make any mistakes while dramatically simplifying it for this post) is working properly and set up using the Streamed transfer mode over the net.tcp protocol. The problem is that the performance is significantly worse than downloading the same file through IIS over http. Why would this b...

To this end I have put together a simple WCF service that allows for simple querying and I am currently wiring this up to a textbox, listbox combination ...
In trying to deploy a service I have found that it won't start because MSMQ is in workgroup mode.
