Hello all!

I am new to Web API and C#. I have watched most videos on API (Bruce Marc and others). I want to develop web api that can be consumed
by any client not just powerbuilder app, Client app will send just one row at a time. So I am assuming caller will send POST with arguments.

Requirements:
I want to validate few field before the updating the database.

So I created a datawindow and a NVO in PB, then in snapdevelop I created Controller, services and  impl through Scaffolding. The NVO also been converted as class in this project. 

Q: How/Where do I call the nvo's function or tie my NVO in a services ?
