How to change language?

[denis-ivanov]

Question

We have localized app that uses OpenID authorization. And when the user tries to log in, we want to open a login page with the same language that was in our client app. For example, I authorized in STS and set French language. Then I opened our app, it uses English language. When I try to log in, I want to see a page with English language, but I see French.

options.Events.OnRedirectToIdentityProvider = context =>
{
    context.ProtocolMessage.UiLocales = Thread.CurrentThread.CurrentUICulture.TwoLetterISOLanguageName;
    return Task.CompletedTask;
};

I thought it should help, but it does not affect login page language.

P.S. Thanks for the project.
