A demo overriding Exceptional error list
Sample of some files I whipped up to try and demonstrate how to provide a

Raw
Controllers\ErrorsController.cs
public class ErrorsController : Controller
{
//The stock handler. Still needed to get the default CSS and JS used for Exceptional
public async Task Exceptions() => await StackExchange.Exceptional.ExceptionalMiddleware.HandleRequestAsync(HttpContext);
}
