Sample enum:

    public enum Countries
    {
        Australia = 0,
        [Description("United Kingdom")]
        UnitedKingdom = 1,
        [Description("United States")]
        UnitedStates = 2,
        [Description("New Zeland")]
        NewZeland = 3
    }

Mvc dropdown list:

ViewBag.Regions = new SelectList(EnumHelper.EnumerateDrop<Countries>(), "Key", "Value");

In _ViewImports.cshtml add @using static <NAMESPACE_OF_HELPERS>.EnumHelper
In mvc view file get enum text:

@model.Country.Description()
