c# - How to return 401 instead of 302 in ASP.NET Core?

Question

I'm trying to get ASP.NET Core Identity to return 401 when a user isn't logged in. I've added an [Authorize] attribute to my method and instead of returning 401 it returns 302. I've tried a ton of suggestions but nothing seems to work, including services.Configure and app.UseCookieAuthentication setting LoginPath to null or PathString.Empty.

Answer 1

As of ASP.NET Core 2.x:

services.ConfigureApplicationCookie(options =>
{
    options.Events.OnRedirectToLogin = context =>
    {
        context.Response.StatusCode = 401;    
        return Task.CompletedTask;
    };
});
