How do I set the locale for an ASP.NET 5 application?

Question

I’m trying to do a blanket override of the host locale for an ASP.NET 5 web application. Most solutions refer to the <globalization/> web.config element, but this is IIS-specific and doesn't seem to fit the new ASP.NET model.

I tried:

app.Use(next => context => {
    Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("en-AU");
    Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("en-AU");
    return next(context);
});

This gets executed, but this doesn’t seem to have any effect on the request (maybe due to the extensive Tasking in the pipeline?) Is there a better way to accomplish this?

The issue is with the async controller. You should set the default culture to all threads instead:

app.Use(next => context => {
    CultureInfo.DefaultThreadCurrentCulture = CultureInfo.GetCultureInfo("en-AU");
    CultureInfo.DefaultThreadCurrentUICulture = CultureInfo.GetCultureInfo("en-AU");

    return next(context);
});

You can actually just put these lines at the top of the Configure method:

CultureInfo.DefaultThreadCurrentCulture = CultureInfo.GetCultureInfo("en-AU");
CultureInfo.DefaultThreadCurrentUICulture = CultureInfo.GetCultureInfo("en-AU");
