i am trying to follow the Layered service Model http://2.bp.blogspot.com/_Ulehi1qz3j0/SDFTyiUkRGI/AAAAAAAAACc/J0UiCKTeKQk/s1600-h/Layered+Service+Model.gif , so Process service should call task service or entity service. now i just instantiate the other service from first one as class instantiation Service2 myOtherService = new Service2(). i know it is wrong, but should i add service reference in service project and call the other service through proxy as i do in web client? thanks in Advance

i am new to wcf and i searched for a moedl to design my services. then i found the layered service model is common , i thought it is good for me. if you have an idea how to design sevices in wcf for enterprize application tell me, but if ESB is an external software may be it is not an option.

hey,

i highly recommend you not to do so.

if you want dynamic coupeling between services, you need each service to be unaware of the other service existance.

i would recommend you to read a bit on ESB, the idea is that you basically create a router service that has a datacontract to all services, and all messages goes through him.

example, you have a service requesting data on "b and c" you send a request for them to the router, he will go to "b" and to "c"
and return their response
