JSONP with ASP.NET Web API

After asking this question, I finally found what I needed, so I am answering it.

I ran across this JsonpMediaTypeFormatter. Add it into the Application_Start of your global.asax by doing this:

var config = GlobalConfiguration.Configuration;
config.Formatters.Insert(0, new JsonpMediaTypeFormatter());

and you are good to go with an JQuery AJAX call that looks like this:

$.ajax({
    url: 'http://myurl.com',
    type: 'GET',
    dataType: 'jsonp',
    success: function (data) {
        alert(data.MyProperty);
    }
})

It seems to work very well.
