Prevent Api from auto return bad request response without firing CustomExceptionFilterAttribute

[Bebarsse]

In case if a controller action with an invalid ModelState , the Api return by default a 400 Bad Request without firing the CustomExceptionFilterAttribute .

The behaviour of the api must be changed with adding services.Configure<ApiBehaviorOptions>(options => { options.SuppressModelStateInvalidFilter = true; }); on the startup class to allow CustomExceptionFilterAttribute handling these exceptions.

Hi @Bebarsse - that is how it is currently configured - https://github.com/JasonGT/NorthwindTraders/blob/master/Northwind.WebUI/Startup.cs.
