title: hl7 components for .net
body: <p>I havea windows service built in .net which must build some hl7, send it off over tcp/ip, receive an ack.  Are there any free libraries for doing this.  I could probably handle the tcp/ip part myself, but if I can find a good library that at least has all the parsing logic to just deliver me a class instance representing the message that would save me a lot of work.</p>
