Applying [JsonIgnore] to property causes DataAnnotation attributes to be “lost”

问题

Given the following code:

    [JsonIgnore]
    [Display(Name = "Loan Cap")]
    public virtual string SomeProperty { get; protected set; }

When the DataAnnotationsModelMetadataProvider.CreateMetadata is called by ASP.NET MVC to fulfil the following call:

@Html.DisplayNameFor(model => model.SomeAttribute)

The list of attributes handed to CreateMetadata does not include the [Display] attribute (or the [JsonIgnore] for that matter). If I remove the [JsonIgnore] then the [Display] gets found and passed to CreateMetadata. Anyone have any idea why this is happening?
