Alright, here's how it is for an object, just tested this: ============================================ASPX==================================

        $("#btngeMethodCallWithAnObjectAsAParameter").click(function (event) {

            $.ajax({
                type: 'POST',
                url: 'Default.aspx/PageMethodCallWithAnObjectAsAParameter',
                data: '{"id":"' + '5' + '", "jSonAsset":' + JSON.stringify(new BuildJSonAsset()) + '}',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (msg) {
                    if (msg.d) {
                        alert(msg.d);
                    }
                },
                error: function () {
                    alert("Error! Try again...");
                }
            });

        });
    });


    function BuildJSonAsset() {
        this.AssetId = '100';
        this.ContentId = '200';
        this.AssetName = 'Asset1';
    }

========================================================================

[WebMethod()]
public static string PageMethodCallWithAnObjectAsAParameter(int id, JSonAsset jSonAsset)
{
    return "Success!";
}

======================================================================

And this works for a single object, next I am going to try a list of objects:)
