First off, i found this:
Generate C# classes from JSON Schema
and although it seems to have the answer. It does not work in .net 4.5+.
I don't want to run compatibility in my application because its using a lot of new API functions.
My goal is to receive the Json, write to file the model.cs and the rest of my application can use it. But is there a library, resource or method to do this for newer applications?
