Web Api ModelState validation is ignoring the DisplayAttribute

Question

Given a model with these data annotations:

public class Example
{
    [Required]
    [Display(Name = "Activity response")]
    public string ActivityResponse { get; set; }
}

I would expect the model state error message to be "The Activity response field is required." Instead it is "The ActivityResponse field is required."

Hooray! The codeplex issue reports that this bug will be fixed in Web API v5.1 Preview.
