JsonRequestBehaviour.AllowGet Not Working - datatables

Question

i am working for JQuery Datatables server side. While creating the json object, to return back, it doesn't allow JsonRequestBehaviour.AllowGet. If code is exactly same what below is, then i am not able to get data in client side.
HTML :
<table class="table table-striped table-bordered table-hover" id="EmployeeTable">
<thead>
<tr>
<th>LastName</th>
</tr>
</thead>
<tbody></tbody>
</table>
JQuery:
$('#EmployeeTable').DataTable({
"processing" : true, // for show progress bar
"serverSide" : true, // for process in server side
"filter" : false, // to disable search box
"orderMulti" : false,// for disable multiple columns at once
"ajax" : {
"url" : "/Employee/GetEmployeeDataTable",
"type" : "post",
"datatype" : "json"
},
"columns" : [
{ "data": "LastName", "orderable": true }
]
});
Server Side:
[HttpPost]
public ActionResult GetEmployeeDataTable()
{
// Get Parameters
//get start(paging start index) and length(page size for paging)
var draw = Request.Form["draw"].FirstOrDefault();
var start = Request.Form["start"].FirstOrDefault();
var length = Request.Form["length"].FirstOrDefault();
//get sort column values
var sortColumn = Request.Form["columns[" + Request.Form["order[0][column]"].FirstOrDefault()+"][name]"].FirstOrDefault();
var sortColumnDir = Request.Form["order[0][dir]"].FirstOrDefault();
int pageSize = length != null ? Convert.ToInt32(length) : 0;
int skip = start != null ? Convert.ToInt32(start) : 0;
int totalRecords = 0;
var employees = getDataService.GetAllEmployees().Select(x => new {
x.LastName
}).ToList();
if(!(string.IsNullOrEmpty(sortColumn) && string.IsNullOrEmpty(sortColumnDir)))
{
employees.OrderBy(x => sortColumn + " " + sortColumnDir);
}
totalRecords = employees.Count();
var data = employees.Skip(skip).Take(pageSize).ToList();
var result = Json(new
{ draw = draw,
recordsFiltered = totalRecords,
recordsTotal = totalRecords,
data = data
});
return result;
}
But if i put like following
var result = Json(new
{ draw = draw,
recordsFiltered = totalRecords,
recordsTotal = totalRecords,
data = data
},JsonRequestBehaviour.AllowGet);
then i can't find this thing in mvc core. Please help me what should i do.

In asp.net core, the Json method does not have an overload which takes JsonRequestBehavior. So you may simply call the Json method with the data you want to pass.
var result = Json(new
{ draw = draw,
recordsFiltered = totalRecords,
recordsTotal = totalRecords,
data = data
});
return result;
