Disabling validation of parameters with [NeverValidate]

[jonmotos]

It would be great if we could disable validation on specific parameters with the existing [NeverValidate] attribute.
Expected behavior from the existing model validation is to:

1. Ignore any classes marked with this attribute
2. Ignore any parameters marked with this attribute

I took a look in the action filter but it appears to be quite difficult to get the attributes of the parameter.

I'd be happy to take a look and implement if there is any interest in this.

Hi Jon, I think it's possible by casting each parameter variable in the foreach (var parameter in controllerActionDescriptor.Parameters) loop at line 51. Did some quick testing and this seems to work;

var parameterAttributes = ((ControllerParameterDescriptor) parameter).ParameterInfo.CustomAttributes;

The if check needs to be adjusted to check if there is a [ValidateNever] attribute present. Furthermore, a new condition needs to be created to check the presence of that attribute on the method and/or class, I think we can use endpoint.Metadata.OfType<FluentValidationAutoValidationAttribute>().Any() for that purpose.

The only thing I am currently debating is whether the check for the [ValidateNever] attribute always needs to fire or only when the DisableBuiltInModelValidation option is set to false.

Did some more digging but this one is becoming rather complex. I am going to push this issue to v1.4 for now.
