Configuration apis using enums are broken in visual studio 16.7+

See original GitHub issue

Describe the bug Starting with 3.0.0 the generator fails when using PropertyNameMappingStrategy.CaseInsensitive with error message.

Could not resolve enum reflection type of PropertyNameMappingStrategy or Riok.Mapperly.Abstractions.PropertyNameMappingStrategy is not supported.

Cleaning and rebuilding as well as cleaning, closing VS and deleting the .vs folder and reopening did not resolve the issue. Everything seems to build fine using the dotnet cli.

To Reproduce Try to build the sample code below from visual studio 2022.

Expected behavior The generator should complete without error and Stringfield should be mapped to StringField

Code snippets

using Riok.Mapperly.Abstractions;

namespace ConsoleApp1
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var mapper = new Mapper();
            var from = new FromObject
            {
                Stringfield = "test"
            };

            var to = mapper.Map(from);

            Console.WriteLine(to.StringField);
        }
    }

    public class FromObject
    {
        public string Stringfield { get; set; }
    }

    public class ToObject
    {
        public string StringField { get; set; }
    }

    [Mapper(PropertyNameMappingStrategy = PropertyNameMappingStrategy.CaseInsensitive)]
    public partial class Mapper
    {
        public partial ToObject Map(FromObject input);
    }
}
