Microsoft.OpenApi.Extensions Enum.GetDisplayName() doesn't work, works fine when copied over-CodePudding

Wanting a quick way to set a display for Enums without creating an enum class, I came across [Display(Name = "display name")] I was going to write my own method but found Microsoft.OpenApi.Extensions.EnumExtensions.GetDisplayName.

public static string GetDisplayName(this Enum enumValue)
{
    var attribute = enumValue.GetAttributeOfType<DisplayAttribute>();
    return attribute == null ? enumValue.ToString() : attribute.Name;
}

It doesn't work, returning the enum.ToString() value, but if I copy over the method as is into my project, it works fine. Any idea why? Running .net 5.0

They check for their own Microsoft.OpenApi.Attributes.DisplayAttribute.

Either roll your own extension method, pointing to Systems.ComponentModel.DataAnnotations.DisplayAttribute, or (less preferably) apply their DisplayAttribute to your enum.
