POST two arrays in JSON to ASP.NET Core MVC 6 -

foreword: have application mvc 4 , .net v4.6.1 , working charm. 1 editor template sends ajax request controller list of things:

function showeffectiverights(e) {     $.ajax({         contenttype: "application/json",         data: json.stringify({             privileges: $("#assignedprivileges").getkendomultiselect().value(),             privilegegroups: $("#assignedgroups").getkendomultiselect().value()         }),         datatype: "json",         success: function (data) {             // stuff         },         error: function (data) {             showresponsemessages(data);         },         type: "post",         url: '@url.action("effectiverights", "user")'     }); } 

the controller looks this:

[acceptverbs(httpverbs.post)] public jsonresult effectiverights([datasourcerequest] datasourcerequest request, guid[] privileges, guid[] privilegegroups) {     // stuff } 

the payload of post request follows:

{"privileges":["d72c1162-0c3d-e611-953e-00155d9e5c08","e32c1162-0c3d-e611-953e-00155d9e5c08"],"privilegegroups":["bb2c1162-0c3d-e611-953e-00155d9e5c08"]}

whenever ajax request sent, variables privileges , privilegegroups have information client. yay!

let's problem. new application should use mvc 6 , .net core. according nuget, every library use up-to-date. javascript same. controller got attribute (it doesn't work acceptverbs either):

[httppost] public jsonresult effectiverights([datasourcerequest] datasourcerequest request, guid[] privileges, guid[] privilegegroups) {     // stuff } 

the payload , request headers of both applications identical. whatever reason, variables privileges , privilegegroups never contain elements.

i've tried add [frombody] did not either.

https://stackoverflow.com/a/38493849/4944034 had similar problem. sent 1 object, have two. , suggest solution did not work me.

what have change make work?

edit have similar on same page. data submitted component kendo. content type application/x-www-form-urlencoded , payload looks this:

profileid=8f96c1bb-5c68-4071-a423-ab2a7ba8234f&selectedprivileges=1410335f-9e35-4454-a7e9-77c7d24bf5df&selectedgroups=60d0ec60-c820-47d7-acea-f4d57f221e5c

the controller able receive 2 arrays:

[httppost] public jsonresult privilegelistforuser([datasourcerequest]datasourcerequest request, guid[] selectedprivileges, guid[] selectedgroups) {     // stuff } 

may due defaultcontractresolver setting in startup.cs?

public void configureservices(iservicecollection services) {     services.addmvc()         .addjsonoptions(options =>         {             options.serializersettings.contractresolver = new defaultcontractresolver();         });      services.addkendo(); } 

best regards, carsten

ps: might have noticed using telerik's kendo. yes, using different versions in both applications. not see, how kendo should interfere here.

create model class , use it:

public class inputmodel {     public guid[] privileges { get; set; }      public guid[] privilegegroups { get; set; } }  [httppost] public jsonresult effectiverights([datasourcerequest] datasourcerequest request, [frombody]inputmodel model) {     // stuff }
