.net - Disable default use of Accept-Language header in ASP.Net Core -

in asp.net core, have following setup per documentation on establishing culture in application:

var supportedcultures = new[] {   new cultureinfo("en-ca"),   new cultureinfo("fr-ca"),   new cultureinfo("fr"),   new cultureinfo("en"),   new cultureinfo("en-us"), };  var defaultrequestculture = configuration["settings:culture:defaultrequestculture"];  if (defaultrequestculture == null) {    defaultrequestculture = "en-ca"; }  app.userequestlocalization(new requestlocalizationoptions {   defaultrequestculture = new requestculture(defaultrequestculture),   supportedcultures = supportedcultures,   supporteduicultures = supportedcultures }); 

i've added settings:culture:defaultrequestculture appsettings.json file can configured on per site installation basis.

this documentation indicates order can changed, unfortunately doesn't provide example on how it.

it indicates these 3 providers used default:

1. querystringrequestcultureprovider
2. cookierequestcultureprovider
3. acceptlanguageheaderrequestcultureprovider

i cannot figure out how disable third. want other ones remain is, application disregard http header entirely.

just you'd remove item ilist<t>.

var localizationoptions = new requestlocalizationoptions {     supportedcultures = ...,     supporteduicultures = ...,     defaultrequestculture = new requestculture("en-us") };  var requestprovider = localizationoptions.requestcultureproviders.oftype<acceptlanguageheaderrequestcultureprovider>().first(); localizationoptions.requestcultureproviders.remove(requestprovider); 

or

var localizationoptions = new requestlocalizationoptions {     supportedcultures = ...,     supporteduicultures = ...,     defaultrequestculture = new requestculture("en-us"),     requestcultureproviders = new list<irequestcultureprovider>     {         // order important, in order evaluated         new querystringrequestcultureprovider(),         new cookierequestcultureprovider()     }; };
