some portion of pass looks this:

 "storecard": {     "headerfields": [       {         "key": "lessons",         "label": "points",         "value": "200"       }     ], 

on update web service call, passed same pass in binary format points value 500. expected output show points 500 instead of 200. see "couldn't update pass" message once refreshing done. testing in iphone4s ios 9.2.1.

i referred: https://github.com/yuchaoonline/ytoo.service/blob/master/dotnet-passbook-master/passbook.sample.web/controllers/passregistrationcontroller.cs

the method binaryformatter() didn't work changed binarymediatypeformatter() per reference https://github.com/horizon-institute/affectivecomputingcloud/blob/master/affectivecomputingcloud/restapiwebrole/formatter/binarymediatypeformatter.cs

i tried following header parameters:

response.content.headers.contenttype = new mediatypeheadervalue("application/vnd.apple.pkpass"); response.content.headers.lastmodified = datetime.utcnow; response.content.headers.contentdisposition = new contentdispositionheadervalue("attachment"); response.content.headers.contentdisposition.filename = "pass.pkpass"; response.content.headers.contentdisposition.name = "pass.pkpass"; 

there seems multiple issues wrong content-type. changing content type application/vnd.apple.pkpass , passing updated pass updated date fixed issue.
