Json, jQuery and ASP.NET MVC

I’m stacking a few things here related to Json, jQuery and ASP.NET MVC so that I can get to them later on.

JQuery to grab some Json when a web page is loaded:

$(document).ready(function() {
    $.getJSON("/MyController/MyJsonAction", null, function(data) {
        //do stuff with data here
    });
});

The smallish code in the ASP.NET MVC controller:

It’s possible to use anonymous types with Json() as well, which is very useful but may be harder to unit test.
