Sorry for the delay in response, I am currently working on a sample to demonstrate this for you and I will make a blog post out of it and let you know when it's published.
I will point you to the most common issue you will have, by default ASP.NET in all it's flavors of dealing with JSON request will require the request type to be POST and the contentType must be "application/json;charset=utf-8".
