amazon web services - SNS GetEndpointAttributes & Publish to Endpoint not available in .Net SDK -

i using v2.5.26.2, runtime version v2.0.50727 of aws sdk .net , noticed getendpointattributes calls not available sns client, nor can target endpoint arn in publish request message.

the documentation api, getendpointattributes method ,for sns indicates should able both of things.

i tired asking question on aws support forums figure out why call not available have yet receive reply more week later.

i tried several web searches problem no avail.

is limitation of .net sdk or perhaps limitation of version using? if so, there workaround make either of these calls.

edit: code samples requested (although not show since objects not getting recognized

getendpointattributes

so according amazon documentation getendpointattributes first need create class derives virtual class getendpointattributes so.

using system; using system.collections.generic; using system.linq; using system.text; using amazon.simplenotificationservice; using amazon.simplenotificationservice.model;  namespace company.project.sns {      public class snsgetendpointattributes : getendpointattributes      {       } } 

which creates following compiler error

the type or namespace name 'getendpointattributes' not found

you should try endpoints subscribed application making request using arn. response contains collection endpoints , attributes, can search match , retrieve attributes:

public dictionary<string, string> getendpointattributes(string platformarn, string endpointarn)     {         var listplatformendpointsrequest = new listendpointsbyplatformapplicationrequest();         listplatformendpointsrequest.platformapplicationarn = platformarn;         var response = snsclient.listendpointsbyplatformapplication(listplatformendpointsrequest);         dictionary<string, string> endpointattributes = response.endpoints.exists(x => x.endpointarn.equals(endpointarn))             ? response.endpoints.find(x => x.endpointarn.equals(endpointarn)).attributes             : null;         return endpointattributes;     } 

i'm not sure mean when can't target endpoint arn, because every time subscribe endpoint should storing arn inside db or that. anyway, here sample publish message if can access endpoint arn:

public void sendmessage(string endpointarn, string message)     {         var request = new publishrequest();         request.message = message;         request.targetarn = endpointarn;          var response = snsclient.publish(request);         return response;     } 

hope you.
