c# - Sending raw WNS notifications using message attributes -

i attempting send raw notification wns setting message attributes, appears toast notification being sent instead.

here c# code i'm using build publish request.

var request = new publishrequest() {     topicarn = topic_arn,     message = "test message",     messageattributes = new dictionary<string, messageattributevalue>()     {         { "aws.sns.mobile.wns.type", new messageattributevalue() { stringvalue = "wns/raw", datatype = "string" } }     } }; 

from can tell, setting x-wns-type correctly using sns message attributes, notification still received toast on client. there examples of doing successfully?

i able working using messagestructure. setting value json , updating message have message wns did trick. assumption wns value messageattributes applies if message defined wns.

var request = new publishrequest() {     topicarn = topic_arn,     message = "{ \"default\": \"default message\", \"wns\" : \"raw message\"}",     messageattributes = new dictionary<string, messageattributevalue>()     {         { "aws.sns.mobile.wns.type", new messageattributevalue() { stringvalue = "wns/raw", datatype = "string" } }     },     messagestructure = "json", };
