当WCF服务和jquery函数在不同的项目中，但在相同的解决方案中，使用jquery调用WCF服务函数

我想在单独的项目中使用jquery函数访问WCF函数。

代码:

<script type="text/javascript">
    $.ajax({
        type: "post",
        url: "http://localhost:3241/EntityService.svc/GetGenders",
        data: '{}',
        contentType: "application/json; charset=utf-8",
        dataType: 'json',
        success: function (result) {
            alert("success..");
            alert(result);
        },
        error: function (a, b, c) { alert(c); },
        failure: function (msg) {
            alert(msg);
        }
    });

</script>

web . config:

WCF服务:

[OperationContract]
gender_obj[] GetGenders();

我总是得到未定义错误。

使用Fiddler，我发现错误数是400
