FlagEnums.GetFlags hangs in .NET Core 3.1.0

[TylerBrinkley]

I'm getting the same behavior. I'm looking into it.

@derigel23 Could you please provide an example so I can research this?

Here it is.

using System;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using EnumsNET;

namespace ConsoleApp1
{
  class Program
  {
    static void Main(string[] args)
    {
      foreach (var enumMember in Enums.GetMembers<Wayspot>(EnumMemberSelection.All | EnumMemberSelection.DisplayOrder))
      {
        var flags = enumMember.GetFlags();
        Console.WriteLine($"{enumMember.Value} = {string.Join(", ", flags.Select(e => e.ToString()))}");
      }
    }
    
    [Flags]
    public enum Wayspot : byte
    {
      [Display(Name = "Pokéstop", GroupName = "static_assets/png/btn_pokestop.png", Order = -10)]
      Pokestop = 1,
      [Display(Name = "Gym", GroupName = "static_assets/png/gymLogo.png", Order = -50)]
      Gym = 2,
      [Display(Name = "EX-Raid Gym", GroupName = "static_assets/png/gymLogo.png", Order = -100)]
      ExRaidGym = 4,
      [Display(Name = "In Queue", GroupName = "static_assets/png/btn_help_nooutline.png")]
      NominationReview = 8,
      [Display(Name = "Rejected", GroupName = "static_assets/png/btn_close_normal_dark.png")]
      NominationRejected = 16,
      [Display(Name = "Accepted", GroupName = "static_assets/png/btn_ok_normal_dark.png")]
      NominationAccepted = 32,
      Other = 128,
    
      [Display(Name = "Wayspots", Order = 1)]
      Wayspots = Pokestop | Gym | ExRaidGym | Other,
      [Display(Name = "Nominations", Order = 2)]
      Nominations = NominationReview | NominationRejected | NominationAccepted
    }

  }
}

As appeared, it doesn't depend on target framework - hangs anywhere,
I've just updated Enums.NET library simultaneously with bumping target framework - that mislead me.

v3.0.3 fixes this issue. This issue only affected flag enums that use an unsigned backing type and where the value is near the underlying type's max value. The commit including this fix is 708e766.
