Aspnetcore.docs: Code sample references nonexistent property ApplyCurrentCultureToResponseHeaders

[grovesNL]

The following code sample appears on this page:

app.UseRequestLocalization(new RequestLocalizationOptions
{
    ApplyCurrentCultureToResponseHeaders = true
});

But the ApplyCurrentCultureToResponseHeaders property described doesn't seem to exist on the RequestLocalizationOptions class, so this code sample fails to build with ASP.NET Core 3.0. The documentation for RequestLocalizationOptions also doesn't reference mention this property.

@grovesNL you're probably missing a package. See https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-3.0&tabs=visual-studio#add-package-references-for-removed-assemblies

Thanks for the quick response and link to the property on master. I think this problem still exists in the 3.0 release though.

This happens when I create a new project with dotnet new web -f netcoreapp3.0 and make that single change in Startup.cs.

The .NET Core 3.0.0 release is tagged at https://github.com/aspnet/AspNetCore/commit/aee5e4080331553ea9dfb7fb388b6d72f715bf6a which doesn't include this property as far as I can tell from https://github.com/aspnet/AspNetCore/blob/aee5e4080331553ea9dfb7fb388b6d72f715bf6a/src/Middleware/Localization/src/RequestLocalizationOptions.cs

The change is in the 5.0.0 branch, which would explain why it isn't working in 3.0.

[hishamco]

If is that shall we remove it from docs?

AFAIK I already started the PR before 3.0 is release I don't know if there's something changed

[Rick-Anderson]

We should remove this from the docs if it's not in 3.0

[hishamco]

Stange!! I'm not sure why this n't shipped in 3.0, @Rick-Anderson I will create a PR for it

[OnurGumus]

Still nothing in 3.1

[hishamco]

Any update on this?!!
