+By default, there are no compile-time checks to ensure that the response metadata specified with a [`[ProducesResponseType]` attribute](xref:Microsoft.AspNetCore.Mvc.ProducesResponseTypeAttribute) is consistent with the actual behavior of the action method, which may return a different status code or response body type than specified by the metadata.

-In controller-based apps, ASP.NET responds with a ProblemDetails response type when model validation fails or when the action method returns a result with a 4xx or 5xx HTTP status code. Validation errors typically use the 400 status code, so you can use the [`[ProducesResponseType]`](xref:Microsoft.AspNetCore.Mvc.ProducesResponseTypeAttribute) attribute to specify the error response for an action, as shown in the following example:

-A special case is when an enum type has the [Flags] attribute, which indicates that the enum can be treated as a bit field; that is, a set of flags. A flags enum with a [JsonConverterAttribute] will be defined as `type: string` in the generated schema with no `enum` property, since the value could be any combination of the enum values.
