Implementation of `IDisplayMetadataProvider` that reads the display name from `JsonProperty` attributes.

JsonPropertyDisplayMetadataProvider.cs

namespace Mvc.Examples
{
    internal class JsonPropertyDisplayMetadataProvider : IDisplayMetadataProvider
    {
        public void CreateDisplayMetadata(DisplayMetadataProviderContext context)
        {
            var attributes = context.Attributes;
            var jsonPropertyAttribute = attributes.OfType<JsonPropertyAttribute>().FirstOrDefault();

            var displayMetadata = context.DisplayMetadata;
            displayMetadata.DisplayName = () => jsonPropertyAttribute.PropertyName;
        }
    }
}
