I am finally experimenting and trying to learn MVC after years of asp.net.
I am used to using asp.net AJAX PageMethods where you can pass an object that automagically gets parsed to whatever type the parameter is in that method.

Javascript:

PageMethods.AddPerson({First:"John",Last:"Doe"});

Code-Behind:

[WebMethod]
public static Result AddPerson(Person objPerson)
{
    return Person.Save();
}

How would do this using MVC and jQuery?
Did just have to send strings and parse the json to object?
