Hi everybody!!!

How do I Make a Master details like this; Person has income and credit history using WebAPI, part of my web api code in c# is....

public class PersonasController : ApiController
{
    CreditosConexion context = new CreditosConexion();

    //get all customer
    [HttpGet]
    public IEnumerable<Persona> Get()
    {
        return context.PersonaSet.AsEnumerable();
    }
}

when I get the structure of Api / GET-api-People this is the result:

Collection of Persona
     Name	Description	Type	Additional information
    PersonaID	integer	 None.

        "IngresosExtrasLaborables": 1.0,
        "OtrosIngresosExtasNoLaborables": 1.0
      }
    ]
  }
]

Angular cannot be used?, can I do it with just MVC?
If I'll use Angular how to make this?

What I have tried:

public class PersonasController : ApiController
{
    CreditosConexion context = new CreditosConexion();

    //get all customer
    [HttpGet]
    public IEnumerable<Persona> Get()
    {
        return context.PersonaSet.AsEnumerable();
    }
}
