A circular reference was detected while serializing an object of type in AngularJs and asp.net mvc - angularjs

Question

Well I know it is well known error. There are lots of questions asked here. But after going through few questions I am not able to solve my problem I am getting this error my website.
This is my error
A circular reference was detected while serializing an object of type
My Controller Code is
[HttpGet]
public JsonResult Get(int currentPage, int recordsPerPage)
{
var pageNumber = currentPage;
var pageSize = recordsPerPage;
var begin = (pageNumber - 1) * pageSize;
var totalNumberOfRecords = db.Products.Count();
var productlist = db.Products.OrderBy(r => r.ProductID).Skip(begin).Take(pageSize).ToList();
db.Configuration.ProxyCreationEnabled = false;
//var productlist = db.Products.ToList();
var product = new { Product = productlist, TotalRecords = totalNumberOfRecords };
return Json(new { Products = productlist, RecordCount = totalNumberOfRecords }, JsonRequestBehavior.AllowGet);
}
My Angular Controller Code is this
function GetProducts() {
var productResult = productService.getProduct($scope.currentPage, $scope.recordsPerPage);
productResult.then(function (result) {
console.log("d",data);
if (result.data != '' || result.data != null) {
if (result.data != null || result.data != '') {
$scope.Products = result.data;
}
else if (result.data = 0) {
$scope.message = "No Product Found"
}
}
});
};
And Angular Service code is this
this.getProduct = function (currentPage, recordsPerPage) {
return $http.get('/Home/Get?currentPage=' + currentPage + '&recordsPerPage=' + recordsPerPage);
// return $http.get('/Home/Get');
};

You should not serialize your entity objects. Your entity objects have virtual navigation properties which are detected by JsonSerializer. JsonSerializer thinks they are embedded properties of that object and tries to serialize them too. and this goes on. serializer finds itself trying to serialize all database. this is why your error occurs.
You should either mark fields that need to be serialized or use DTO's to serialize objects.
Note: you can use AutoMapper to map objects between Entity and DTO
