c# - Xamarin.Auth AccountStore not deleting values? -

whenever call method removes accountstore in xamarin, deletes , says there 1 less thing in list. method below called first dependency service.

public void deletesecurevalue(string appname, string key) {     var account = accountstore.create().findaccountsforservice(appname).firstordefault();     if (account.properties.containskey(key))         account.properties.remove(key);      var props = account.properties;     // when debugging, props doesn't contain value passcode } 

---

xamarin.forms.dependencyservice.get<istoragehandler>().deletesecurevalue(globalconstants.app_name, "passcode");  var account = accountstore.create().findaccountsforservice(globalconstants.app_name).firstordefault(); var props = account.properties; // when debugging, props has value passcode when shouldn't 

why value passcode seem come back?

you manipulating dictionary in memory in deletesecurevalue. have write changes storage.

public void deletesecurevalue(string appname, string key) {     var store = accountstore.create();     var account = accountstore.create().findaccountsforservice(appname).firstordefault();     if (account.properties.containskey(key))     {         account.properties.remove(key);         store.save(account, appname);     } }
