I'm calling a method of my WebAPI sending a json that I would like to match (or bind) with a model.

In the controller I have a method like:

public Result Post([ModelBinder(typeof(CustomModelBinder))]MyClass model);

'MyClass', wich is given as a parameter is an abstract class. I would like that at, depending of the type of json passed, the correct inherited class is instantiated.

To achieve it, I'm trying to implement a custom binder. The problem is that (I don't know if it's very basic but I can't find anything) I don't know how to retrieve the raw Json (or better, some kind of serialization) that comes in the request.

I see:

• actionContext.Request.Content

But all methods are exposed as async. I don't know who this fits with passing the generate model to the controller method...

Thanks a lot!
