Hi everyone!

I need NT Service(ofcource without GUI) but with some networking support(UDP server).
Networking depends on QCoreApplication, but i have no idea how to implement service with QCoreApplication.

My reference service code is here. It works, but how to embed QCoreApplication in it?
May be there is some other way to implement NT service application?
