Fast variant that works for every enum

public static class EnumUtil where TEnum : struct
{
    public static readonly Dictionary _cache;

    static EnumUtil()
    {
        _cache = Enum
            .GetValues(typeof(TEnum))
            .Cast()
            .ToDictionary(x => x, x => string.Format("{0}.{1}", typeof(TEnum).Name, x));
    }

    public static string AsString(TEnum value)
    {
        return _cache[value];
    }
}
