    <PackageReference Include="FontAwesomeAttribute" Version="0.1.0.0" />
  </ItemGroup>

Add using statement in code

using FontAwesome.DataAnnotations;

Add attribute to enum

  public enum Role
  {
    /// <summary>
    /// No role assigned, default user role
    /// </summary>
    [Description("None")]
    [Display(Name = "None")]
    [FontAwesome(Name = "No Roles", FixedWidth = "True", Icon1 = FontAwesome.Css.Ban, IconSize1 = FontAwesome.Size.Normal, Stacked = "False")]
    None,

    /// <summary>
    /// Developer role
    /// </summary>
    [Description("Developer")]
    [Display(Name = "Developer")]
    [FontAwesome(Name = "Developer", FixedWidth = "True", Icon1 = FontAwesome.Css.UserNinja, IconSize1 = FontAwesome.Size.Normal, Stacked = "False")]
    Developer,
  }

          var attributes = fieldInfo.GetCustomAttributes(typeof(TCustomAttr), false).ToList();

          if (attributes.Any())
          {
            return (TCustomAttr)attributes[0];
          }
        }
        catch (Exception)
        {
        }

Use in code

  string item = "Developer";
  Role role = (Enum.Parse<Role>(item, false));

  var faIconName = role.ExtractAttribute<FontAwesome.DataAnnotations.FontAwesomeAttribute, Role>().Css;
  var roleName = role.ExtractAttribute<System.ComponentModel.DataAnnotations.DisplayAttribute, Role>().Name;

Use in markup

  <li class="navbar-light"><i class="@(faIconName) pe-4"></i>@roleName</li>
