You may download sql.msmq.dll [http://www.yankeeboysoftware.com/Stuff/sql2msmq.dll here] You will undoubtably find that there is some dependency that I have missed. Please do not hesistate to let me know. I wanted to do a click once deployment, but it doesn't seem to be compatible with SqlServer type projects Again, if you know anything that might make this whole mess easier, I'd love to know about it. If you wish to provide feed back, please register. You will have '''New Ticket''' permission immediately. Raise a ticket against 'jack' and I will respond. Thanks. Jack
