Through an HttpResponseMessage MVC4 successfully sends an AngularJs controller $scope of GetAllFolders().

A Folder in the collection has among other things and association to the Photo class.

Folders can be folders of other folders (self-referencing).

Debugging shows from MVC4 side all is good and correct detail information was returned.

But through Angular/Json, certain properties are $ref tag and can not be seen, as example:

enter image description here

I do not care much for creating a method call on FkPhotoId and hit the server for the image name when I know it was already sent in the first response.

Any ideas?

UPDATE: SOLUTION

This code was added in the global.asax: (make sure you reference it in the start method)

    public static void ConfigureApi(HttpConfiguration config)
    {
        var json = config.Formatters.JsonFormatter;
        config.Formatters.Remove(config.Formatters.XmlFormatter);
        config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore; 
    }

enter image description here

Resolution from OP (housecleaning - marking so can mark answered) This code was added in the global.asax: (make sure you reference it in the start method)

public static void ConfigureApi(HttpConfiguration config)
{
    var json = config.Formatters.JsonFormatter;
    config.Formatters.Remove(config.Formatters.XmlFormatter);
    config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore; 
}

Just to add my two cents. I had this extra line in my code that was also causing this issue

config.Formatters.JsonFormatter.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;

Thanks digger69 for this one.
